I need help with UE5's landscape: Blueprint visibility brush

As some of you know there is a experimental landscape plugin called “Landscape Patch”. Which just essentially modifies/levels the terrain around a special component added to any actor.

So I’m using PCG graphs to randomly spawn actors into the world. At the center of the actors the “Patch Component” levels and smooths the terrain. But I also need to hide a small portion of the terrain, so the player can go beneath it. Unfortunately it’s not possible to do everything by hand, as there are almost a hundred placed all over the terrain, and they’re randomly generated.

I was wondering if anyone knows of a way I could hide the terrain and disable the collision just like the landscape visibility brush tool does?
