did you mean that you want to see Windows Hello for Business page when you use Azure AD account signing in the devices?
1.Did you refer to the following article to enable Windows Hello for Business?
https://learn.microsoft.com/en-us/mem/intune/protect/windows-hello
- Yes, I did went through this article and enabled it. and double checked it when asked by Azure Chat support before posting it the question here. Please see screenshot.

2.Could you please check if you set "Users may join devices to Azure AD" to "All" in Azure AD portal > Devices > Device settings?
- Yes it was set to "All". Please see screenshot.

3.Please try to check if there is any detailed error message in the device's event viewer > Applications and Services Logs > Microsoft > Windows > DeviceManagement-Enterprise-Diagnostic-Provider
- I removed the AD join and re-join it to Azure AD and got errors:
- error 404:
MDM ConfigurationManager: Command failure status. Configuration Source ID: (D561953F-4052-4AAF-858E-1C078A28EAC2), Enrollment Name: (MDMDeviceWithAAD), Provider Name: (Policy), Command Type: (Add: from Replace or Add), CSP URI: (./Device/Vendor/MSFT/Policy/ConfigOperations/ADMXInstall/Receiver/Properties/Policy/FakePolicy/Version), Result: (The system cannot find the file specified.).

- error 454: MDM ConfigurationManager: Command failure status. Configuraton Source ID: (D561953F-4052-4AAF-858E-1C078A28EAC2), Enrollment Type: (MDMDeviceWithAAD), CSP Name: (DMClient), Command Type: (Add: from Replace or Add), Result: (./Vendor/MSFT/DMClient/Provider/MS DM Server/EntDMID).

Even with these errors, the Azure AD join was successful, but still NO prompt for Windows Hello for Business enrollment.
Also, when I go to Intune portal >> All devices >> the VM >> Device configuration: there is no data/policy.
