Boot Flags "stuck" in NVRAM

[gabevf]

I've been trying to switch from Clover to OpenCore without success, so no I'm trying to go back to Clover but I noticed that the boot arguments from OpenCore have carried over to Clover.

Resetting the NVRAM from an OC bootable drive does not work.
re-writing the flags in the Clover Boot screen options doesn't work.

Where are these Boot arguments stored in NVRAM?
is there a way to force delete them from terminal?

Thanks in advance!

Ok, I was able to change it by resetting the CMOS on the motherboard.

Unfortunately none of the tools above, nor the following seemed to work: Hackintool, "sudo nvram -c" terminal command, F11 key during clover boot screen....

Really not sure wha't going on, but those going from OpenCore to clover (or vise-versa), please beware!
