There is archaeological evidence of a large-scale invasion (not just a "migration") in Baluchistan around 2000 BC. Despite superficial similarities with Indo-Aryans, I propose the invaders are unrelated to both Indo-Aryan and Dravidian while also introducing horses separately from Indo-Aryans.
Around 2000 BC, there appears to have been large-scale destruction and abandonment of settlements in the Baluchistan uplands and the Kachi plain, which lies between the Bolan Pass and the Indus river valley. This has been noted by several archaeologists since the latter half of 20th century, as summarized by Coningham and Young, The Archaeology of South Asia (2015), p.257:

It is quite tempting to connect these events with the Indo-European invasions/migrations (I don't believe in a stark distinction between "invasion" and "migration"), as superficially the archaeological remains show possible connections with Indo-Europeans:
- After a clearly violent event involving the destruction of walls and various objects, the site of Gumla in the Gomal valley had a notable presence of horse bones and horse figurines.
- Figurines of bulls were also found alongside horses, indicating an importance of cattle for the invaders (who were likely nomadic pastoralists).
- Graves in the latest period of occupation at Mehrgarh, a very ancient site near the Bolan Pass, show similarities with some graves in Iran and Central Asia.
- Graves show that cremation was practiced, as we know was practiced in Indo-Aryan culture alongside burial in the earliest times.
However, neither the geography nor the timeline seems to be a good fit for Indo-European movements. We know that the Indo-Aryans established themselves not in Baluchistan, but further to the north and east in Punjab and Haryana. These invaders seemed to have instead moved along a more southerly axis, and also seem to have predated Indo-Europeans by at least a few centuries.
In fact, there is very little evidence of early Indo-Aryan presence or influence of any sort in Baluchistan or even the lower Indus. The only material culture that might be associated with the early Indo-Aryans, before the advent of PGW, is the Punjab-centric Cemetery H culture. Baluchistan does not have much if any links with probable Indo-Aryan cultures until late Period IIB and Period III at Pirak in the Kachi plain (very late 2nd millennium and early 1st millennium BC), where we find grey ware that might be connected with Iron Age PGW (cf. J.G. Shaffer in Ehrich, Chronologies in Old World Archaeology, 459). The site of Pirak is notable for being continuously occupied from c.2000-800 BC (i.e., immediately after the aforementioned destruction and abandonment of settlements) and for having terracotta figures of camels, horses, and riders from the earliest period of occupation as well as remains of camel and horse bones. (cf. R.H. Meadow, "A preliminary note on the faunal remains from Pirak", 334)
If these mysterious invaders were not related to Indo-Europeans, could they have been related to the Proto-Dravidians? That seems even more unlikely. It is almost certain that Proto-Dravidian was spread by the Southern Neolithic culture, which had already dispersed throughout the Deccan Plateau by the 3rd millennium BC. These Neolithic pioneers in South India were cattle-centric pastoralists much like the Indo-Aryans but, crucially, did not have horses. By the time our mysterious invaders were penetrating into the Baluchistan uplands, it is likely that the ancestors of Dravidian languages already had a strong presence in the South. Thus, the timeline mismatch here is even greater than with the Indo-European migrations.
Given the lack of any clear evidence of Indo-European settlement in Baluchistan immediately after the disintegration of IVC, as well as the lack of any evidence connecting late IVC Baluchistan with the Proto-Dravidians, this opens the possibility of totally unrelated non-Aryan migrants with some possible connection to Iran and Central Asia introducing horses and settling down in Baluchistan in a manner analogous but separate from the later Indo-Aryans. In this context, it is worth noting that Dravidians in South India seem to have adopted horses independently from the Indo-Aryans, as we find elaborate elite-centric horse burials and horse furniture in Early Iron Age South India, long before any notable Indo-European influence in South India. (cf. J.R. McIntosh, "Dating the South Indian megaliths" in South Asian Archaeology 1983, p.475)
In fact, every major Dravidian languages has their own indigenous word for 'horse' that is totally separate from Proto-Indo-European, and moreover, many Indo-Aryan languages in North India seem to use a word for 'horse' that is totally unrelated to Proto-Indo-European but possibly related to Dravidian via a third language source. For example, consider Telugu guṟṟamu, Punjabi ghuṭṭ, and Hindi ghoṛā. These words and many others are quite likely related, but probably not via Old Indo-Aryan directly borrowing from some older Dravidian word for "horse". Rather, it seems that the ancestor of Hindi and Punjabi and the ancestor of Telugu both borrowed words for "horse" from a similar third source that was neither Dravidian nor Indo-European. Given that the earliest Indo-Aryans clearly already had their own word for 'horse' that was derived from PIE (Indo-Aryan aśva < PIE h₁éḱwos; cf. Avestan aspa), the fact that non-Aryan words for 'horse' predominate in Indo-Aryan languages is quite striking and is consistent with an older, separate introduction of the horse into the subcontinent.
