LadyLinux nice suggestion!
on install we just generate the rndc key to be used in the future, so we can easily add a flag for that first in create_rdnc().
and for user panel it already respects the dns option in enabled_features to display anything dns related.
so the only work to be done is in opencli commands to check that dns option first., and on admin panel to skip dns zone edit.
I'll add this as a new github issue
