Question Change bind/named ports

Hi,
we need to change the ports bin9 is listening on on a Plesk-System.
This applies to both, the DNS-Port (53) and the RNDC-Port (953).

In the file /var/named/run-root/etc/named.conf there is a special section for custom directives, however bind doesn't allow to overwrite already existing blocks. In the block provided by Plesk there is already an "options"-directive, so it's not possible to add another one. However listen-on has to be places inside options.
We may add another rndc-port by adding an additional controls-block: contols allows for multiple blocks to be present, however those are simply added and don't overwrite previous blocks.

The DNS-Port may also be changed by adding -p <newport> to the file /etc/systemd/system/bind9.service.d/plesk.conf, though this doesn't help in changing the rndc-port.

Is there a way to change those ports in a different way? Maybe some option in panel.ini, or changing a plesk config file?
