At this point, even to say that “the rinnegan can only be awakened by reproducing Hag’s chakra” is not a correct statement since there are characters like Momoshiki out there who most likely had his rinnegan way before Hagoromo got his. So the rinnegan either is something specific to some Otsutsuki and their chakra or (more likely) is derived from the powers of the God Trees since Hagoromo was the son of Kaguya who awakened rinne sharingan after consuming thr God Fruit and Momoshiki has a whole history of consuming chakra fruits himself.
