How to make AI Detour Controller ignore player?

I have a bunch of NPCs in a crowd using AI Detour Controllers to move around, and I want them to completely ignore the player. But even if I set both the player and NPCs’ collision to ignore the other, the AI Detour Controller still paths around the player.

I looked around for the solution to this, and the best I could find was this thread (Detour Avoidance Groups - AI - Unreal Engine Forums) which seems to be a good solution for C++, but I’m working entirely with blueprints. Is there a blueprint-based way to tell the AI Detour Controller to completely ignore certain actors?
