Set MAC or IP on Homebidge interface

I have a question about one of the network interfaces in my Homebridge app/container. I followed the writeup to add Homebridge as an app here:

Homebridge on TrueNAS Scale · homebridge/docker-homebridge Wiki · GitHub

My question is that there are 2 interfaces. The one on net0, which is the one that actually talks to my network is the one I’m interested in. Since it uses DHCP, it’s pulling the address form my router, which is fine. The problem is that every time the container restarts, this interface gets a new MAC address, which causes the router to issue it a different IP address. This makes it a bit hard to keep up with which address I can currently access the Homebridge GUI from when I need to update plugins. Is there some way I can make this interface have the same MAC address every time?
