Hi cyb3rmik3,
Thank you for your reply!
I can understand the MDE documentation and the method you described, that is, the prerequisite for disabling defender is to manually disable tampering protection first. However, as described in my question, it is unacceptable and unreliable for enterprises to manually disable tampering protection for at least thousands of operating systems.
So I want to know if there is a way similar to Windows 11 where you can turn off Defender by registering a third-party anti malware product with WSC, even if tampering protection is already enabled.
By the way, we have joined Microsoft's MVI organization and consulted with them, but there is no reliable method.
