Zigbee2mqtt remote

Good afternoon. I have a Qnap Nas with Hassios installed and a sonoff coordinator and zigbeemqtt installed. This is at the entrance of my house.
On the other hand I have a powerful server away from the entrance of the house and connected to the Nas by mosquitto in bridge mode to see the zigbee devices.
I would like to be able to have zigbee2mqtt installed on the powerful server while keeping the coordinator on the nas at the entrance.

I have Hassios and I can’t install ser2net on the new versions.
Can someone tell me how to do it?

Thanks in advance to all the community.
