Windows 10 1709 - Defender detects Forticlient 5.6 and refuses to have defender be primary real time

Problem:

If Forticlient 5.6 is installed and configured to have real time scanning disabled, in Windows 1709 defender forces its own real time scan to be disabled.

 

The problem is the Forticlient is used for firewall policy enforcement so we really want to use it.

 

Is there a way, through either Windows Intune or Defender ATP to configure that defender is primary threat protection?

 

Thanks!
