Unfortunately, the iGPU is not visible with default BIOS values (iGPU deactivated) and if I set the iGPU to active in BIOS, I cannot boot anymore and need to clear CMOS to boot again…

I'm having issues flashing bios to F11.
Ive updated bmc to the newest version.
Bios flashing says complete, bmc restarts and bios is still on F06.
Flashed it 4 times successfully and still no go.
CPU needs bios update to function, so bmc is my only way to do this...
Anyone have any suggestions?
