@Abhinay Pal, Thanks for posting in Q&A. From your description, I know the Windows 11 update is not installed.
For the windows update ring policy, I notice you already check the registry keys. If the policy is not working as expected, then you need to contact windows update support to look into the issue:
For feature update policy, if the device is not updated to windows 11, then you can look into the feature update report to get more information.
Hope the above information can help.
