Unless you configure your BIND server to validate anyway using one recursive and one authoritative view, e.g.:

acl clients { 192.0.2.0/24; };

view "recursive" {
        match-clients { clients; };
        match-recursive-only yes;
        recursion yes;
};

view "authoritative" {
        match-clients { any; };
        recursion no;
};
