Make camera unable to see class/actor

I am making a game where the person in VR will fly around and shoot pillars, but I wanted to add a twist. I want what is displayed on the game mirror to include the pillars, but the person in VR would not be able to see them.

(This is (one of) my first post(s) Please tell me how I could format it better, or if I need clarification)

Thanks,
