The default behavior is for Early Launch Antimalware - Boot-Start Driver Initialization policy to enforce "Good, unknown and bad but critical" (preventing "bad").
If this needs to be corrected or a more secure setting is desired, configure the policy value for Computer Configuration >> Administrative Templates >> System >> Early Launch Antimalware >> "Boot-Start Driver Initialization Policy" to "Not Configured" or "Enabled" with any option other than "All" selected.
