How to add aa to flags, setting AUTHORITY to 1

[anthonybe98]

Hello,
When I do a dig command I get this answer:

; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 58836
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1

I'm trying to add the flag "aa" and change authority to 1 . The response should look like:

; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 58836
;; flags: qr rd ra aa; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1

Any tips on how to do that? Couldn't find it in the documentation.
Thanks!
