I implemented gpt partitioning tool capable to format partitions/devices
and submitted that to the UEFI community a while ago
(I am away from my PC until next Monday, so you need to search for it
(UefiShellGptCommandLib) if it is urgent for you).
With that one you format your SD card with
gpt fatformat YOUR_SD_SHELL_BLK_ALIAS from within the UEFI Shell.

Thank you,
Vladimir
