Kaguya gained the Rinne Sharingan after eating the Chakra Fruit, both Rinne Sharingan and Byakugan are dojutsu, which means it would make sense for the Rinne Sharingan to be a mutation from the Byakugan. The Chakra Fruit contains Sage Chakra, so according to this logic it would make sense for the Rinne Sharingan to be a mutation from the combination of the Byakugan and the Sage Chakra from the Chakra Fruit.

That's how I see it anyway.
