yes but most likely also with J2b2 and G2a, the former directly from Yamnaya, the latter picked up along the way to the proto-Hellenic homeland in the southern Balkans
there was a linguist, Martinet I think, who quite presciently suggested the Hellenes as a mixture of the Kurgans/Indo-Europeans and the remnants of the Balkanic large scale proto-civilizations of the Trypillians/etc..., and indeed by 2000BC in northern Greece you have people of this kind, 40% something Kurgan, 60% Balkan EEF

mostly up to date instances of J2b in ancient DNA from Europe
