Six paths senjutsu is activated by all jinchuriki and pseudo jinchuriki of ten tails as Madara, Naruto and Obito has it. So it can only be activated or kept activated as long as you have tailed beast inside you and when they are gone you lose it just like Naruto lost after his battle with Sasuke.

Tenseigan is a real dojutsu, and Hamura had it first as far as we know.

"A passage in the movie's novelisation can be read as the energy vessel having been created after Hamura's death, to preserve the power he wielded in life. Conversely, Retsu no Sho states that the energy vessel was created while Hamura was alive and at his direction.[1] As such, it is unclear whether or not Hamura possessed the dōjutsu version of the Tenseigan, and if he did what he used it for. "

Hamura most likely sealed his Tenseigan into the vessel first, making it the Tenseigan Vessel.. then other Byakugan were added giving the Vessel more power.

So Toneri could just find Hamura's eyes and insert them into himself instead of absorbing hundreds of eyes into himself?) But you need Hamura's chakra to touch tenseigan energy vessel which Hinata had not toneri as mentioned in https://naruto.fandom.com/wiki/Tenseigan_(Energy_Vessel)
