How do I allow players to alter Object Responses of collision via a lever?

Specifically, I want to toggle Object Responses of a volume’s collision via an interactable object. I want a lever that alters a volume’s collision.

I am making a volume wherein the time dilation affects different things based on a lever’s state. If the lever is one way, objects/projectiles (WorldStatic) pass through the volume very slowly. If the lever is another way, only the player (Pawn) passes through slowly.

I’m using this tutorial for the time dilation set up. How do I adjust what is affected via the lever?
