UEFI is focused on defining the interfaces to option ROMs and OS loaders, and pushing policy decisions, where possible, in the platform firmware. UEFI tends to not define how the construct the platform Firmware. The UEFI PI specs go into more detail of firmware construction, but mostly so modules can interoperate. PI does not focus on things that are higher level platform firmware features.
The PI terminology is FD (Flash Device) and there is no way to access the FD programmatically. The platform firmware produces FVs (Firmware Volumes) out of the FD in PEI (memory discovery/S3) and DXE (EFI services) phases. The FV containing the SEC and PEI Core are often executed directly from the FD, but most other FVs are compressed. This is all done via platform specific code.
