How to prevent 2 dynamic rigid bodies from pushing each other?

[TheMetaverseEngineer]

Hi, I want to know how to prevent 2 rigid bodies from pushing each other. I read about the dominance group in the documentation but that only works for only 1 rigid body. imagine if the 2 rigid bodies are moving toward each other and none can push the other one. is there any solution?

Colliders are responsible for detecting collisions between objects, not rigid bodies. Take a look at collision groups; that should be able to do what you need. For instance, you could set membership and filter for the first object to group 1, and set them to group 2 for the second object; then they won't collide with each other and will pass through each other instead.
