What program is used to see the hidden functions of each bios? I would like to try it
@sagaelI don't know, @Lost_N_BIOS done it for me (different laptop) some time ago with textual output of BIOS options so you can use efi shell to enable/disable without modding the BIOS (in some bios)Link to the post:ACPI mod request for vga Intel UHD Graphics 600 detection (3)
try this method at the time but without success as my current bios has no hidden option to modify igpu behavior
