One way collision response?

I have now run into this problem multiple times and I figure the solution to this problem to be trivial, but for the life of me I can not find an answer online or figure it out myself.

What I want to do is to have a movable physicalized object affect other physicalized objects, but not be affected by them. In essence have the specific objects collision response be ignore/overlap towards other movable objects but other objects that have the specific objects response channel set to block be blocked by it.Or in a simpler more abstract way: give the specific object infinite mass (I have kinda made this work in one instance but it was way adhock and still problematic).

Sample: a spaceship that pushes away debris that come into contact with it, but its own velocity/impulse would remain unchanged.
