Execute command as user

I would like to Execute a command/commands as user, similar to Execute-ProcessAsUser
I want to Execute this command Get-AppxPackage -Name [APPNAME] | Remove-AppxPackage
for a number of Apps
script needs to run from SCCM and therefore it is running as System

This might help: Run Get-AppxPackage -AllUsers *appxname* | Remove-AppxPackage" as system permission (SCCM Software Center)
