@Sebastian Wathen Thanks for posting in Q&A. In fact, for the Android Enterprise, the device needs to be in Android Enterprise supported list in the following link:
https://androidenterprisepartners.withgoogle.com/devices
Note: Non-Microsoft link, just for the reference.
If the device is not in the list, then we can't enroll it with Android Enterprise. Based on my researching, the Microsoft Teams Rooms on Android now not support Android Enterprise. It only supports Android device administrator enrollment method. Here is a link with more details for your reference.
Hope the above information can help.
