Collision filtering within articulation root

Hello! I’m working on a vise assembly in Isaac Sim and would like to only enable collision between the opposing vise plates and nothing else. The whole structure is grouped under an Articulation Root with self collision turned off. Is there a way to selectively enable collision for just the two opposing vice plates? I’ve explored using Collision Groups but didn’t have much luck. If you have any ideas or better ways to structure things lmk!
