pack.incompatible.graphics.pbr and greyed out deffered settings

I'm using POCO M4 with Mali-G57, import 2 pbr shader and none of them work because deffered technical preview renderer are greyed out, also an error pack.incompatible.graphics.pbr in each pack import log (on notification window, it says import successful with warning in each of them)

List PBR test shader :

• Vanilla PBR-Light
• Lynx Deffered PBR

• I also have a test phone with adreno 512 and it worked fine but not with the one with Mali
