I can't seem to stop the "Windows Defender Antivirus Service" from running via services.msc, Stop-Service, etc. but I can prevent if from starting after reboot.

Adding this reg key will stop the "Windows Defender Antivirus Service" from running at startup. This PS one-liner will add the key. After adding the key, reboot and the service should be stopped.
