nanite displacement tessellation : decrease triangle density based on distance/screensize

Hi
adding displacement tessellation to a landscape doesn’t reduce the amount of triangle invalidate all the nanite performance boost, there is any way to optimize this by editor or editing the naniteTesselation.sh shader?

NO DISPLACEMENT:


ADD TESSELATION

unfortunately using r.Nanite.MaxPixelsPerEdge command doesn’t reduce the tessellated triangles
