[Technitium] Cannot find settings.json file - add network interface

[jimstratus]

I installed Technitium DNS as a container using the PromoxVE Helper script. I am trying to add a network interface (which is on a different bridge) so I can have Technitium serve as a DHCP server for that interface only. I can't locate settings.json on this container anywhere. I did see that most of technitium is either found in /opt/technitium/dns or /etc/dns but I still don't see the crucial settings.json that I need.

Any assistance in this would be appreciated!
