Can I disable or uninstall Defender AV with Field Effect MDR?

Defender will automatically be de-registered as the primary AV in Windows Security Center when FE AV is enabled. Field Effect MDR’s combination of signature and behavioral threat analysis will quarantine malicious files pre-execution and block malicious processes at runtime, providing the protection needed to eliminate malware before it can cause disruption but can additionally run alongside Defender AV for a layered defense.
