CSVDE has no relationship to PowerShell. It has been around well before PowerShell and is a completely stand alone executable. Can you use external executables in PowerShell scripts, sure, but each have their particulars unrelated to PowerShell.
You do not need to install or even enable RSAT on yours or any system to use the AD cmdlets.
You just need to be able to establish a remoting session to a server that has it (a domain controller or backup domain controller or why server / workstation that has RSAT installed). There are a few ways to use AD cmdlets without installing / enabling RSAT tools on a system.
This is fully documented in the built-in help files and on the web...
It's call PowerShell Remoting. To use it, it must be allowed on the server that has the cmdlets enabled in most remoting scenarios, you must be a local admin on a remote host.
About Remote SHORT DESCRIPTION

$san = 'user'
($getad = (([adsisearcher]"(&(objectCategory=User)(samaccountname=$san))").findall()).properties)
