Banks cant do it, and banks really cant bear the pressure of the establishment and state policies, But CEXs can as they offer their services worldwide so they don't accept much pressure from the state if a state is enforcing them with their terms they can simply quit their service there but Banks cant quit they will compromise as their Bussnies domain is the state specifically with some exceptions but Banks really cant, giving benefit of the doubt if they can why they are not doing so.
I'm pretty sure some banks also quite servicing one or two countries when the regulations are no longer friendly to them. Especially if they are not based in that country, to begin with. While it is harder for them to completely move from one country to another, I'm pretty sure regulation is the key reason for that. I would not be surprised if exchanges will also have the same problem sooner or later.
At the end of the day, moving to a hybrid platform won't remove the risk that the platform will control your funds. I believe if security and control are your priority, any kind of CEX or hybrid CEX is not an ideal choice.
