nope madara can deactivate his rinnegan thats how he put raikage in genjustu.It is his Rinnegan, Hagoromo gave Sasuke "power" which equated into the Rinnegan for Sasuke. Naruto got a new mode which is also his. What I would argue isnt theirs are the seals on their hands.
Also Madara is also unable to deactivate his own Rinnegan, which leads to the conclusion you simply cannot deactivate it.
