Are there no better options for registry keys in Intune ?

We're currently in a hybrid setup, working hard to shit all workstations to Intune.

However we struggle with having hundreds of registry keys that need to be set and maintained. Yes they are meaningful in our environnement, and most of them need to keep existing.

We've tried script with remediation (not available with Business Premium by the way), and we've tried customs ADMX imported.

It's a hassle, it's complex and nowhere near as straightforward as GPO for registry keys.

What is everyone out there doing for efficient registry management ?
