@Darren Ramos, Thanks for posting in Q&A. For our issue, we can firstly check the registry keys under the following location to see if the setting has been deployed to the device.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\current\device\Update.
Meanwhile, please check if there's any GPO with update policy set on the device. As I know, GPO will win over Intune policy to take effect.
If the related registry key in the above location is created, but it is still not working. That means the issue is on windows devices side. You can check the WindowsUpdateClient event log to see if there's any more finding.
Hope the above information can help
