The official way to do this is found here: https://github.com/dotnet/deployment-tools/tree/main/src/clickonce/native/projects/NetCoreCheck

This is what the WiX team is doing:

For now, the lazy way to do this is to include the installer and run it every time. If it's already installed then it does nothing. This uses the installer as the checker, which is ham fisted and slow but gets the job done.

Here is an example for .NET6 Desktop 6.0.9

Get installer: https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-6.0.9-windows-x64-installer

Section "Install .NET6 Desktop Runtime"
  File /oname="$TEMP\windowsdesktop-runtime-6.0.9-win-x64.exe" windowsdesktop-runtime-6.0.9-win-x64.exe
  ExecWait "$TEMP\windowsdesktop-runtime-6.0.9-win-x64.exe /install /quiet /norestart"
  Delete "$TEMP\windowsdesktop-runtime-6.0.9-win-x64.exe"
