To do this, one must set a registry entry, this is Powershell:
$registryPath = "HKLM:\SYSTEM\Setup\MoSetup";
If ( !(Test-Path $registryPath) ) { New-Item -Path $registryPath -Force; };
New-ItemProperty -Path $registryPath -Name "AllowUpgradesWithUnsupportedTPMOrCPU" -Value 1 -PropertyType DWORD -Force;
then download the ISO (not the recommended upgrader app), unpack it, and run setup.exe.
