How to make NPCs ignore collision with each other

I have an island that is Survival Horror Co-op versus NPCs. Problem is that right now, NPCs can block each other, which causes their pathfinder to bug out, making them circle around endlessly at the same spot.
I could write some extensive checks to fix this issue or simply allow them to walk through each other, like you could do in Unreal.

Is this possible to do in UEFN?
