I checked on the Redfish Schema Supplement document and saw attributes 
from the Memory, Pcie, ... schema are read-only. It means no POST/PATCH 
action is supported now.

How's about suggesting on supporting POST/PATCH action with the needed 
information change to read-write? UEFI will then collect data and send 
Redfish commands via the Redfish Host Interface.
