"It is possible to manifest a new Tenseigan by combining the chakra of Hamura's descendants within the Ōtsutsuki and Hyūga clans."

"The clan uses the energy vessel as an energy source to power everything on the moon, including the countless autonomous puppets that served them"

The vessel is not used to create the Tenseigan, it just stores countless Byakugan to combine their power and store natural energy. Toneri has the chakra of Hamura (an Otsutuski member) because he is an ancestor of him and then he steals the Byakugan from Hanabi, thus unlocking the Tenseigan. All it requires is the mixture of chakra from a Hyuga and a Otsutsuki. Bhav fulfills both of these requirements.
