Differentiate actual DfC/DfE license usage on Windows systems

Trying to understand on how the Windows endpoint(server/laptops) licenses are being used in my environment and for that,  trying to figure out how to check the number of on-prem/azure cloud systems deployed with Microsoft Defender for Endpoint or Defender for server P2 license? Like where and how can i see which are the assets that are getting configured DfS license and which systems have been configured with MS DfE?
