On a secure platform you likely need to update using a secure capsule.
https://github.com/tianocore/tianocore.github.io/wiki/Capsule-Based-Firmware-Update-and-Firmware-Recovery
The capsule is the standard method, and then all the FLASH update code is part of the ROM.
Generally since an EFI platform has NVRAM services in the NOR FLASH there is an SPI driver to write to FLASH.
So if your platform does not secure FLASH you can use the services from the ROM.
