@Benj Salvador, Thanks for posting in Q&A. From your description, I know you want to deploy Shared multi-user device.to the deice group and want to know how we can enroll these devices before we deploy the profile.
Based as I know, for the above profile, this is mainly for devices which are shared with many users. There are many enrollment methods support to deploy this profile. You can see more detailed in the following link:

DEM is generally used for the shared device. You can enroll via DEM which is mentioned by Marcin.
Hope the above information can help.
Best regards.
Crystal
