Other Intune-related topics, including unsupported scenarios and platform-specific behaviors
@Anjeela Sthapit, Thanks for posting in Q&A. If the users already have local admin right, it can install applications by default. I suggest removing the local administrators for the users and only keep the users you want in the local administrators group by Local user group membership policy.
To let standard users to install some applications that require elevated privileges, EPM is an option.
