Windows Defender enabled by default on Windows Server 2016

I was working on a Windows Server 2016 system that I had already configured and put in production.  While I was monitoring the resources of the server when I noticed the processes for Windows Defender show up in the task manager as if it were scanning files.  This server already had a different AV solution installed.
As it turns out, you need to uninstall Windows Defender feature manually on Windows Server 2016 (‚Äč).  Windows Server 2016 will not disable Windows Defender automatically.
"On Windows Server 2016, Windows Defender AV will not enter passive or disabled mode if you have also installed a third-party antivirus product. If you install a third-party antivirus product, you should uninstall Windows Defender AV on Windows Server 2016 to prevent problems caused by having multiple antivirus products installed on a machine."
