@padmgb,Thanks for posting in Q&A.
For your issue, Azure AD Premium P1 does not include Intune licenses, however, Microsoft 365 for enterprise includes Microsoft Intune and E5 also includes the Azure AD premium plans 1 and 2. It also offers the highest level of security and threat protection of all the Microsoft 365 subscriptions. And if you want to enroll your devices into Intune, it is suggested that your subscriptions include Enterprise Mobility + Security E5.
