My first boot with this bios settings was okay! I will feedback you later!Maybe I found a workaround, but needs some more test.
On my Asus X299-A Prime, disabling Serial Port in Bios -> Advanced -> Onboard Devices seems to fix the problem.
I rebooted 7 times yesterday and 3 times this morning. During night I unplug from the power outlet.
As for now I haven't got any black screen, usually I got a couple every 3-4 good reboot.e
I read that others with the same issue have fixed by disabling Serial Port in bios. For what I remember on Catalina amend Mojave I had the Serial Port disabled but before upgrading to BigSur I decided to upgrade also the Bios and decide to leave Serial Port on since I thought it did not give any problem.
