i looked to see if board had q flash plus. I don't see any results that show it does.
Q flash needs you to be able to see BIOS
Q Flash + would have worked had you had feature on board. It lets you flash bios with nothing apart from power.
could ask Gigabyte to confirm but I don't see it mentioned in manual or searches.
looks like its mostly on AMD boards.. i see it on Z690 boards though.
There is no listing of what has it, that is the problem.
Aye, Secure boot on Gigabyte boards is something different. As Colif already mentioned we could tell it's Gigabyte even without you naming the board. There is one thing that can be tried before resorting to sending the board for reprogramming the BIOS - using the iGPU. In your case it means temporarily obtaining different CPU that had integrated graphics. However it is impossible to tell if that will work (as the board may indeed be bricked). So if you know somebody that can borrow you 10th gen non-F CPU (possibly even 11th gen depending on what BIOS version your board has) it might be worth trying. Otherwise, time to search for a repair shop.
