How to disable Metahuman Face setup and features?

So I’ve been doing some research into optimization and realized my game thread was bottlenecking my performance heavily. Among the things reducing fps, it seems like the MetaHuman face is causing massive gamethread drops as you can see in the picture below.

The issue is that my game is “true” first person, meaning you can never see the MetaHuman’s face. In the BP I have the face not render in the base pass so the camera can see through.

I don’t need the face to have any kind of setup on the gamethread beyond rendering in shadows, which means it doesn’t need rigging, can use the lowest LOD, etc. How would I accomplish removing all of those features without breaking anything?
