But why? It makes no sense because the Edo's have unlimited chakra, so they wouldn't need to turn it off. And I seriously doubt that toggling a Dojutsu Kekkei Genkai on and off is such a high level skill that an Edo can't do it with a real Rinnegan.

SP in known for making this kind of mistakes like when Sasuke was able to deffer Shadow Clones with Sharingan in filler, and yes Kishi was only script supervisor and character designer this kind erros may be not even reflected in script and Sasuke design still had Rinnegan ativated. Fact remains no one ever turned off real Rinnegan in Manga.

I agree with this based off the Manga. I think a user can momentarily activate a lesser dojutsu kekkei genkai and cast a technique, while their Rinnegan is in fact still active, but I don't believe it can be activated and deactivated at will.
