This includes Basic integrity checking but also attempts to build a trusted boot chain.
BootProtect	None Boostrap	Attempt to provide bootloader persistence None Enables usage of Bootstrap.efi in the directory EFI/OC/Bootstrap instead of BOOTx64.efi. This setting is helpful for users using rEFInd to boot or avoid BOOTx64.efi overwrites from Windows. Bootstrap *For this option to work RequestBootVarRouting is required to be enabled.* *Use of Bootstrap option will also enable "OpenCore" instead of UEFI: OS followed by your drive name in Boot Menu.*
DmgLoading	Disabled Signed Any	Define Disk Image (DMG) loading policy used for macOS Recovery. Disabled Disables loading of DMG images. Disabled policy will still let macOS Recovery to load in most cases as there usually are boot.efi files compatible with Apple Secure Boot. Manually downloaded DMG images stored in com.apple.recovery.boot directories will not load. Signed Enables only Apple-signed DMG images will load. Due to Apple Secure Boot design Signed policy will let any Apple-signed macOS Recovery to load regardless of Apple Secure Boot state, which may not always be desired. *It's recommended to set this option to "Signed" to avoid issues.* Any Enables any DMG images will mount as normal filesystems. Any policy is strongly not recommended and will cause a boot failure when Apple Secure Boot is activated.
SecureBootModel	Default Disabled	Defines Apple Secure Boot hardware model. Sets Apple Secure Boot hardware model and policy. Specifying this value defines which operating systems will be bootable. Operating systems shipped before the specified model was released will not boot. Default Enables Default Secure Boot.
