What we would love to see is the ability to send the Site Secret Key and other optional values directly with the MDM Profile to the Mac the same way we do it with iPadOS and iOS (see screenshot). Like this we could skip the Deployment script and just push the package to the Mac the same way we normally distribute software.

It would also be very convenient for the scoping of different sites. Then we could use the same install policy for all Macs and would just have to create different MDM Profiles for different device groups.
