I have two instances of HA running. My router will only allow me to port forward one device’s IP to 443

For example, 192.168.0.2, Router Port forwarding - Port 443 to Port 443.

I can forward the second instance of HA (192.168.0.3) Router Port forwarding - Port 444 to Port 444.

Is it possible to change the NGINX Home Assistant SSL proxy default setting of Network
444 /tcp

192.168.0.2 - PI1.duckdns.org

Number 2:
192.168.0.3 - PI2.duckdns.org
Router Port forwarding - Port 444 to Port 444
