Minimal responses and speeding up queries

[Job]

Hello,

in Bind 9.10 we tried minimal-responses = yes to limit "additional queries" when resolving.

I notice that resolution is faster.
Actually, dig @host some_url still shows an additional query, maybe not needed for a caching-only resolver:

; (1 server found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 54581
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1

Is there a way to improve limiting of "additional queries" after minimal-responses = yes?

Thank you
Francesco
