How to hide bone on SkeletalMesh only for main camera?

Hello everyone!

I have issue, thats is visibility of head on SkeletalMesh. I just want to hide that. I tried to use Hide Bone by Name (which scales the bone to 0). But in my game there are render targets (cameras) that draws player without the head.
Maybe there are another ways to hide bones but draw it on render targets and reflections?
There are also flag on components Visible in Reflection Captures, it will be great if there way to hide bones like this way.

P.S. It’s VR game with full body tracking (some models has eyes and mouth, it looks very crazy in HMD).
