How to remove unknown devices in Microsoft Defender 365?

N-M 186 Reputation points

I connected Microsoft Defender 365 to Endpoint recently.
After 3 weeks, I face too many devices that are not in Endpoint anymore. Maybe there were before. These devices have different statuses. MEM doesn't manage them. Some of them are active, and others not.
I would like to remove these devices. I cannot run the script on them because I don't have access to them or know where they are or whose devices are.
Moreover, these devices are not onboarded. Their onboarding statuses for these devices are "can be onboarded."
It would be great if you could give me some solution to this problem.

    This data is collected by device discovery. You can add exclusions. Once a device is recognized you need to wait 14 days for them to drop from the view once excluded or disconnected.
