Passthrough and Blend Modes?

Checking to make sure this is or isn't possible before I waste much more time on this.

Does Quest 3 mixed reality support blend modes that affect the passthrough layer? I have materials set to "add" but they only add with other virtual objects in the scene, and not on the passthrough background. I usually rely on blend modes for my AR projects with effects like particles, rays of light, and shadows, so this is a really important and powerful part of making projects look immersive!

Image below demonstrates the idea, materials set to add, they blend with each other, and an alpha fresnel which works fine, but they don't add onto the passthrough.
