Installed build on Mac for Apple silicon only (actually compile both platforms)

Hello,
I try to make an installed build of Unreal sources on my Macbook Pro M2. It compiles both architectures so it’s very long. How to only compile the sources for the Apple silicon please?

Haven’t completed the build yet but you can edit one line in InstalledEngineBuild.xml and remove x64 <Property Name**=“MacArchitectureArg” Value=**“-architecture=arm64” />
