@Julien Deroche , For the built-in report for Device Compliance in Intune, description is not included as a filter.
From the Compliance Overview report In Power BI, I find there's no description in the table as well. For our request, we can feedback it on uservoice:

If the description is for Compliance policy, as a workaround, we can check the "Device status" of the compliance policy with the description we want to get the information.
Hope it can help.
