BootSourceOverrideEnabled usage in ComputerSystems Instance

Hi,

BootSourceOverrideMode, BootSourceOverrideTarget values is applicable only when we set BootSourceOverrideEnabled to once or Continuous.

Do we need to allow patch  BootSourceOverrideEnabled , BootSourceOverrideMode, BootSourceOverrideTarget  to /redfish/v1/Systems/Instance or /redfish/v1/Systems/Instance/Settings?
What is the use of displaying BootSourceOverrideEnabled , BootSourceOverrideMode, BootSourceOverrideTarget in Systems.Instance if we allow to patch in /redfish/v1/Systems/Instance/Settings?
Do we have options to know current BootSourceOverrideMode available in BIOS using standard attribute?

Copied definition of attribute from ComputerSystem.v1_17_0.json

"longDescription": "This property shall contain the source to boot the system from, overriding the normal boot order. The @redfish.AllowableValues annotation specifies the valid values for this property. `UefiTarget` indicates to boot from the UEFI device path found in UefiTargetBootSourceOverride. `UefiBootNext` indicates to boot from the UEFI BootOptionReference found in BootNext. Virtual devices for a target should take precedence over a physical device. Systems may attempt to boot from multiple devices that share a target identifier. Changes to this property do not alter the BIOS persistent boot order configuration.",
