  • Confused

excuse my english

Bought this laptop to install macOS Monterey with OpenCore which works. But the BIOS is catastrophically minimized
I need access for:
CFG Lock
DVMT
RAID
UART

can someone unlock the bios completely?

This is for existing but hidden options, there is no hint of changing the speed / voltage in the BIOS. But the hub / processor itself must be able to do this.
