Onboard devices in Purview is grayed out

Thank you for the response. The information around this topic is confusing at first. Your guidance helped point me in the right direction. It turns out the issue wasn’t technical at all, it was related to licensing. After acquiring M365 E5 licenses, I was able to onboard devices successfully.

I’m also sharing a couple of links here that explain this in more detail, in case it helps anyone else who runs into the same problem in the future.
