It seems that a rigid body function is missing.

While working with Blender's rigid body system, I have identified a missing functionality. At present, rigid bodies only support collision with explicitly specified groups, and lack the ability to exclude specific groups from collision calculations. The only available workaround for this is to use rigid body constraints to disable collisions between target objects, which unfortunately causes significant performance degradation. I propose adding a feature that allows the current rigid body to exclude collisions with rigid bodies in a specified group
