Upgraded URP to HRDP but having challenges rendering terrain

[EJMB100]

Hello, I upgraded my unity project from URP to HDRP. Gaia Manager found no issues with the rending settings after following the recommendations. Used Unity Render Pipeline Wizard and fixed all found in the HDRP + VR tab. I've updated materials via the edit>render>HD render pipeline> upgrade from builtin pipeline>upgrade project material to HDRP. The image below shows terrain in white and trees in magenta.  What other steps  do I need to take to be able to correct terrain? Do I need to deal with any of the fixes for HDRP + DXR? Do i need to activate?

Pls advise.
