The log snippet below doesn't say it is loading the key twice. It
indicates that it attempting to configure two separate command
channels.

First mistake: you should not be editing files in /lib/systemd/.
Instead copy the file to edit into /etc/systemd/, and edit it there. I
believe there is a systemd command that will do that for you if
necessary. The reason is that when an upgrade comes along, it will
stomp on any changes you have made in /lib/systemd/.

It looks like it is successfully configuring its command channel on
IPv4 (127.0.0.1#953), and unsuccessfully on IPv6 (::1#953). If you
don't care about IPv6, you can probably ignore that.

I don't see all of those messages on my bind9 installation's log. I am
running bind9	1:9.16.27-1~deb11u1
