Try this:
Insert the MCT USB drive and the USB drive with the unzipped Intel drivers. Alternatively, you can copy the .inf files to the root directory of the MCT USB drive to make it simpler.
Start Windows installation but don't load the drivers, instead at that point press Shift + F10 to get a cmd prompt.
Type pnputil /add-driver x:\*.inf (x being the MCT or the USB drive with the drivers on it).
When completed, type pnputil /scan-devices
Then pnputil -enum-drivers and continue installation, lets see what happens.
If that fails, repeat using a Windows 10 MCT, if that works we'll know that W11 is the culprit.
Then you can upgrade to W11 via the Windows Installation Assistant
