Hi,
then please just don't do it. You are under no obligation to answer,
As we say in Italy: "To ask is allowed, to answer is a courtesy",
but once you take the time and effort to answer then it would
make more sense to me to share your knowledge rather than
tell me why you don't want to share it.
On the other hand if many people in the last 20 years wouldn't
have answered some of my questions I would still be a novice.
On this particular question just to make It clear I've searched
in the opennic wiki and expected to find a file that can be
downloaded like the one for root hints from
https://www.internic.net/domain/named.cache

and also the example in https://wiki.opennic.org/tier_2_unbound seems
not work:

dig . NS @75.127.96.89

; <<>> DiG 9.11.5-P4-5.1+deb10u3-Debian <<>> . NS @75.127.96.89
;; global options: +cmd
;; connection timed out; no servers could be reached

but the example posted by dimitris does (thank you!):

dig . NS @161.97.219.84
