hp All in one 11th Gen core i7 blanck screen

Hello all,

I have Hp All in one 11th gen Tiger lake cpu with core i7. I know it does not support IGPU, but EFI is not showing on the start and instead there is a balck screen. Plz help me if anyone has overcome this problem. Thanks.

NOTE: It cant even show the picker.
