MDE endpoint to Purview onboarding

Hi All,

I have Microsoft defender endpoint plan 2 onboarded endpoints in my organisation, as a new dlp functionality i need to test purview DLP functionality for few of my endpoints but i see that it needs to be enabled the device onboarding in microsoft purview under settings, and it also says that all MDE endpoints will populate automatically here and onboarded since they alreay have MDE, now my worry is, if i enable this and all endpoints start onboarding under purview automatically and if we start facing any difficulty with enspoints how to stop or rollback that since no. of endpoints are more than 500. although i have checked there are no DLP settings or policies configured in the purview. is there any way to include only few endpoints to purview and test before enabling the tenant level button?

is there a way we can disable the button if we enable it and we start encountring any issues with endpoints?

Appreciate help on this.

Thanks
