@Matt Dillon Thanks for posting in our Q&A.
Honestly, I didn't find there is any article about using a provisioning package for Microsoft Entra Hybrid Join. Not sure if it works.
DEM can be used to enroll shared devices. However, it has some limitations.

And there is no easy way to automate this. We need to use DEM account to enroll devices same as a normal Entra ID account.
