Hide head on full body metahuman preview mesh?

Hi, I’m trying to figure out how to hide the head/face on the metahuman full body preview mesh.

I was hoping to use an opacity map- However the UV’s have the face section within 0-1 space but the body section beyond 0-1 space (they work, but in a seperate UV tile, 1-2) . So any map seems to affect both the head and the body simultaneously.

Is there any way of masking out the area in the 0-1 space but not the area beyond? It seems the UV information is there, just not all in 0-1. It’s along story but i’d prefer not to export to another app if at all possible.

Hope that makes sense?!
