LegionZero wrote: Rinnegan has Sharingan abilities but it also adds a bunch more powers. And yes you need a Sharingan and Hagoromo's chakra. No one with a Rinnegan did so without having a Sharingan. Also the Rimmegan cannot be shut off. Hagoromo and Sasuke never have theirs deactivated and Madara did it once as an Edo, which did not have his true eyes. Sasuke deactivated his in The Last (Which I wonder how canon it is, but considering Toneri appeared to talk with Boruto, I am pretty sure using this as evidence is fine), as well after Madara was revived, after defeating Kaguya, when he was dying both his eyes were black, showing his rinnegan deactivated, so yes it can be deactivated. I can provide a picture of both cases if you still doubt it.

EDIT: As it was said here many time, the only requirement to get a Rinnegan is to recreate Hagoromo's chakra, it was never emplied a seperate Dojutsu was required. Ever. Furthermore I highly doubt all of Indra's reincarnates were Uchihas so the Sharingan does not need even be involved at all.
