We have numerous options so you can choose the best way to enable or disable real-time protection.
1: Windows Security Setting
2: Edit the Registry or Use Registry Files
3: Group Policy Editor
4: PowerShell or Command Prompt
1: Windows Security Settings
Click on Windows Security in the system tray found in the lower-right corner of your screen. Click on Virus & threat protection and on the next screen, click on Manage settings under Virus & threat protection.
Toggle On or Off under Real-time protection. Click
Turning real-time protection back on is as easy as clicking on the Windows Security tray icon again and click Turn on. You can also click on the notification that popped up to quickly enable real-time protection again.

Set the Value data to 1 to disable and delete the DWORD you created to enable.

Open Group Policy Editor. Windows 10 Home users can enable Group Policy Editor.
Expand Computer Configuration > Administrative Templates > Windows Components > Windows Defender Antivirus > Real-time Protection.
