I have now managed it myself:

Powershell:
Set-ItemProperty -Path ‘HKLM:\Software\Microsoft\Windows NT\CurrentVersion’ -Name EditionID -Type String -Value Professional;Set-ItemProperty -Path ‘HKLM: \Software\Microsoft\Windows NT\CurrentVersion’ -Name ProductName “Windows 10 Pro”;Set-ItemProperty -Path “HKLM:\Software\Microsoft\Windows NT\CurrentVersion” -Name CompositionEditionID -Value “Enterprise”

And then I took an official Windows 11 Enterprise 22H3 ISO to do the update without any problems.
