Hi Devid, it is not absolutely necessary if there are no compatibility or stability problems. My problem was that no network driver was found (BIOS update did nothing). I had to install the driver during the Windows installation.
Maybe the problem would not have happened with a more recent Windows 11 version.

I have not performed a Bios update. I installed Windows 11 Pro. There were no problems at all.
When installing Windows 11 Pro, you do not need a network driver or network connection during the installation,
you can bypass the step during the network request by "clicking on skip step".
With the Windows 11 Home version, however, a network connection is required, otherwise Windows cannot be installed.
After installing Windows 11 Pro, I installed the normal mainboard drivers.
I did not carry out a bios update at any time and it was not necessary.

Whar Bi me not yet necessary.... ironically

Yes of course, hi
