Not really 100℅ proof if he does or doesn't tho I don't see why they'd be mutually exclusive. Sasuke met the conditions for Hagoromo to manifest with Hashirama's cells (probably got some chakra from Kurama in one of their collabs, e.g. Majestic Attire). Hagoromo ensures that Sasuke can manifest both Dojutsu in one eye. Hagoromo shaped the power that Sasuke naturally awoke.

After all, the conditions to meet Hagoromo are Indra+Ashura+Kurama. Madara never possessed all three at the same time (well until he was a living god).
