Hey everyone! I'm trying to switch the Microsoft 365 update channel from 'Current' to 'Monthly Enterprise', but I'm running into some issues. We're deploying M365 apps using SCCM, and I have a deployment script set up with PSADT. There's a .xml config file from config.office.com, which is supposed to set the channel to Monthly Enterprise.
The settings in the Microsoft 365 admin center confirm this change, but I'm not using Intune for M365 apps—only using SCCM for Endpoint Clients and Intune for managing iPhones.
I have a script that runs daily through Compliance Baseline on client machines to change the registry for the M365 update channel. After updating, some clients seem to revert back to the old channel even after successfully changing it. I'm tracking this with the Device Collection in SCCM but noticed that the number of clients has jumped from 228 back to 270.
Does anyone have advice on what else I can check or if I'm missing something in my approach?

It might be a good idea to disable the compliance setting to make things easier. The M365 management is often more effective when you handle configurations directly through the Office apps admin center, where you can manage updates and channels more effectively. Reassigning devices to the Monthly Enterprise channel through that site is pretty straightforward.
My first guess would be that the Cloud Update option in the M365 Apps admin center is enabled. If it is, it can override your registry settings and SCCM script without you realizing it. Make sure to check if this is active for your devices and, if it is, disable that profile.
If the channel keeps reverting, it's likely that something else is enforcing it. Make sure to check for any conflicting Group Policies or SCCM baselines that might be overriding your script. Sometimes these policies can be sneaky and win out over what you’ve set up.
