I got here having the same problem. I want to display bigger objects like whole rooms (architectural structures), but the occlusion of real objects/real space keeps making these objects invisible over the boundaries. As I found out on a StackOverflow forum, it isn't possible to turn that feature in QuickLook. In case you want to turn on/off Occlusion you have to use ARKit/RealityKit frameworks, meaning you have to built your application yourself.
