Nanite Shadow Fallback Artefacts - Still visible through Glass

I am having issues with the nanite fallback mesh artefacts.

It’s a known fact that nanite can cause weird shadow glitches due to the fallback mesh as explained here:

Even when the issue is “Fixed” (r.RayTracing.Shadows.EnableTwoSidedGeometry 0), the issue can still be seen through glass. Any idea how to fix this? Here example looking from inside out through the glass, and being outside (no artefacts to be seen).
