I think we should continue the loop when BootOrder == NULL, we should not just
return.
Suggest to combine the condition check in following line:
If (EFI_ERROR(Status) || (BootOrder == NULL)) {
continue;
}

Same here, I think we should not return directly.
Combine the check in following line:
If (!EFI_ERROR(Status) && (Variable != NULL)) {
DumpKeyOption (...);
else {
