Hi deepak goyal,
Hope everything is going well.
Per my experience, it's expected behavior for your Windows 11 Home laptop. Because Device Guard is enterprise feature and is not available for Windows 11 Home edition. For more information, we can refer to: Windows 10 Device Guard and Credential Guard Demystified
If you need more information, you can also contact Windows 11 forum to get more accurate help. Here is the link:

Hope it helps. Thanks for your time.
Best regards,
Simon
