Other Intune-related topics, including unsupported scenarios and platform-specific behaviors
@TechUST, Thanks for posting in Q&A.
We can deploy a PowerShell script to add the account to administrator groups.
Create a .ps1 file and with the below script, then upload the script into Intune and deploy it to device.
net localgroup administrators /add "AzureAD\UserUpn"

Or create a custom policy using ConfigureGroupMembership setting to add the account to Administrator groups, then the account will own admin rights.
