Hello,
So, I found a way to delete the inner verts, the drawback is that it requires raycasting and double Frosting. Relies on shooting a ray from vert along the normal, if it hits the surface at distance bigger than the radius - delete the vert. Ray gets shot against a copy of the Frost, with a minimal negative push applied.
Here’s a test scene:

Would be great if Frost could do that on its own, in a more optimized way, so it’s faster
