How to prevent culling on PCG Foliage when rendering using Path Tracer?

Hi,
I am currently using UE5.2 for a project. I have set up PCG to put down grass in areas of the dwelling however when I run a test Path Trace render the grass, if you go back a certain distance, starts to cull. I have switched off Culling, heck I even had switched off LOD but if you have a look from the screen shot I have taken it’s still wanting to cull. When not using Path Tracer it’s fine it’s only when needing to render out with Path Trace. Any clues as to what I might be missing?

Thanks

Still having issues with this. Still scratching my head, anyone have any other clues?

Try this in the console:
r.RayTracing.Geometry.InstancedStaticMeshes.Culling 0
