All that is stated is Sixth Paths Chakra is specific to Hagoromo, and that it is his special Chakra that can only be achieved in certain ways. Hamura's special chakra isn't even stated to be Six Paths Chakra, but something similar.

What I think? Six Paths is likely to be connected to Kaguya and is the true form of the Shinju's (Tree) Chakra. Hagoromo initially only had Sixth Path Yang and Hamura had Yin. Becoming the Jinchuriki allowed him to wield both and thus achieve what we call Six Paths Chakra.

And as we can see from Momoshiki and Kinshiki who never awoken Rinne-Sharingan, every Shinju tree is different when someone eats their fruit. I firmly believe Six Paths is the special Chakra coming from Earth's Shinju.
