By the way, I remembered about Urashiki. He had two Rinnegans and could deactivate them. The Otsutsuky play by difderent rules than most people. Momoshiki obtained 3 Rinnegan from eating Kinshiki and Kinshiki had no Rinnegan

And what do you mean when you say that a fake Rinnegan can be deactivated? How is he different from the real Rinnegan? As an Edo, Madara didnt have his true Rinnegan eyes. They were created by Edo Tensei. Since they were fake he couldnt summon the Gedo Mazo. Maybe they had different rules

The biggest peices of evidence that it cant be turned off by humans/hybrids are Sasuke and Hagoromo. Their stuff is always on even when they dont need it.
