Hello,
I’ve been scratching my head trying to enable the secure boot configuration menu of my Razer Blade 17" from 2021 (model number RZ09-0406). The official BIOS firmware is available for download and I’ve already used tools like UEFITool and IFRExtractor to see what is guarding that menu by default.
I tried toggling the CFG LOCK bit using setup_var.efi, but after looking more at the extracted IFR, I noticed that the submenu is gated behind a var called RDMODE which is sadly in the write-protected portion of the firmware, at least according to the output of setup_var.efi.
Anyone have any ideas how I can best move forward? I would really like to be able to use secure boot on my NixOS partition, if possible.
