You can disable it. First you have to disable the tamper protection and real time protection in the GUI. Now the real time protection will come back automatically in some time, unless you do the following.

If you have a Pro version of Windows there is a group policy setting for it. [1]

If you have Home, you can achieve the same effect by manually tweaking the registry. [2]

--

[1] Computer Configuration > Administrative Templates > Windows Components > Windows Defender Antivirus > Real-time Protection

[2] HKLM\SOFTWARE\Policies\Microsoft\Windows Defender\Real-Time Protection\"DisableRealtimeMonitoring"=dword:00000001

Thank you, I just disabled it on my fully offline game system. Hopefully a few games that previously crashed will work now :/.
