Enable Depth Tracking in a specific real world region - XR Passthrough

Using unity MetaXR depth API with Quest 3, I have a requirement to enable depth API inside a particular place in real room (For Anchoring Im trying to use Controllers) For context, I have a real life object which I do not want to be occluded but others i do. If we can define even something simple like occlude over 1m on real world y axis.
