Q
EFI Shell Redirect standard error (2>) function does not work.
A

"2>" this comment is not standard UEFI shell command. If user want to verify stderr on efi shell, user can write a application and print msg to stderr.

EDKII is a open source for everyone to develop. The following link for your reference.

If user want to redirect msg to stderr, user have to use SystemTable->StdErr, not SystemTable->ConOut.
