Is there a way to disable the automatic vis occlusion on certain objects?

Is there a way to disable the automatic vis occlusion on certain objects?

I have a movable statue and walls made of segments and when you stand at certain positions, the walls behind the statue disappear even though you can see them (well you should, if they wouldn’t disappear of course).

There are also doors which open within half a second. They open so fast you can still see the floor tiles (also separate objects) loading slower than needed.

If there is a way, what keywords should I be looking for?

I haven’t been able to find anything that allows you to disable it for individual objects yet myself but you could disable occlusion culling until a solution is found.
Perhaps using precomputed visibility.
