Actually there already existed a takeaway powershell script to you can make use of.
You can easily find them in How to switch UAC level
Hopefully, it can help.
Edit
The code from the mentioned Microsoft Technet site implements these cmdlets:
- Set-UACLevel()
- Get-UACLevel()
But they are not confirmed for this OS (12. Jan. 2017):
- Windows Server 2012 R2
- Windows Server 2008
- Windows 7
