A way to exclude plugin format target for a particular exporter?

I have a Projucer project with iOS and macOS exporters. I need to build AUv3 for iOS, but would like to avoid building AUv3 for macOS - I don’t need it and it messes with what plugin format hosts ‘see’ when I build the aggregate macOS target.

Is there anything I can do to exclude the AUv3 target from the macOS project besides manually checking and unchecking the format before export?
