Multiple moving CC characters in UE 5.6 causing VSM (Virtual Shadow Map) errors

I have a scene with 3 CC characters in motion and it’s causing VSM (virtual shadow map) errors in UE 5.6. I’m using Lumen (which, in tandem, uses VSM) in my project.

Specific error: “Non-nanite marking job queue overflow. Performance may be affected. This occurs when many non-nanite meshes cover a large area of the shadow map.

Of course, can’t/should not enable UE nanite on character meshes. Further research says to try re-creating the physics assets, but it doesn’t allow this (is this Auto Setup?)
