Almost. In edk2 platforms, the agent that does this is usually not a separate DXE driver, but the given platform's PlatformBootManagerLib instance, which is linked into, and called from, BdsDxe. For two examples, please see PlatformRegisterFvBootOption() in: - ArmVirtPkg/Library/PlatformBootManagerLib/PlatformBm.c - OvmfPkg/Library/PlatformBootManagerLib/BdsPlatform.c A related function is RemoveStaleFvFileOptions(), in both.
