enabled with Pre-boot measurements. This option is set to Off by default.
When TPM 2.0 is installed, TPM 2 Algorithm option is available. It enables you to
select a hash algorithm from those supported by the TPM (SHA1, SHA256). TPM
2 Algorithm option must be set to SHA256, to enable TXT.
Power Button

Recovery Delay is selected.
UEFI Variable Access
Provides varying degrees of securing UEFI variables. When set to Standard (the
default), UEFI variables are accessible in the operating system per the UEFI
specification. When set to Controlled, selected UEFI variables are protected in
the environment and new UEFI boot entries are forced to be at the end of the
current boot order.
In-Band Manageability Interface
When set to Disabled, this setting will hide the Management Engine's (ME), HECI
devices, and the system's IPMI devices from the operating system. This prevents
the operating system from changing the ME power capping settings, and blocks
access to all in-band management tools. All management should be managed
through out-of-band. This option is set to Enabled by default.
