Is the scene geometry OcclusionMaterial accessible in RealityKit?

Is it possible to turn on and off different occlusion material when using Scene Understanding with LiDAR and RealityKit?

For example, if ARKit identifies a wall, I don't want that mesh to be used during occlusion (but I do want occlusion for other things, like the couch or the floor)

If I could do this, it would essentially make my walls transparent, and I could see the RealityKit objects that extend beyond the room I am in.

Thanks,
