How do i delete opencore from uefi boot order section?

I installed macos catalina successfully then went ahead and followed a tutorial to dualboot with windows first boot was fine second boot i could get keyboard and trackpad to work but it worked if i booted from external hdd opencore that i used to install catalina, but no input when using opencore from my laptop efi that i installed and now no matter what i cannot uninstall it i even deleted efi partition on windows and rendered windows unable to boot everything efi related got deleted in bios including my ubuntu mint boot order but opencore is still there... I have tried searching on google but there is only guide from macos and not windows, now i can not even boot into macos
