I looked into this for iPXE. From memory, it wasn't easily possible:
the shell handle numbers conceptually exist only within that invocation
of the shell, and don't represent any property of the underlying handle.
If it helps,
http://git.ipxe.org/ipxe.git/blob/HEAD:/src/interface/efi/efi_debug.c
shows the code that iPXE uses to dump out meaningful labels for
arbitrary handles. This generates names such as:
PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)
ConIn
wdsmgfw
and when no descriptive naming scheme can be found, falls back to
dumping the raw handle and a list of installed protocols, such as
UNKNOWN<0x3f0df318,SimpleTextIn,SimpleTextInEx>
