Get-process does not enumerate all procesess, get error permission denied even when run as admin

There are some process modules that I am getting error for, like permission denied and cannot enumerate for processes like Services, Idle, csrss. It appears there are processes whose modules fundamentally cannot be enumerated due to lack of permissions, even when running with elevation (as admin). How and what permission need to be obtained to be able to enumerate these processes.

Cmdlet executed: Invoke-Command -Session $session -ScriptBlock { Get-Process -Module } and for local just Get-Process -Module
