At the moment I'm using Debian 11 as the main system and Ubuntu 18.04 as the system for virtualization, I do all the management through Cockpit.
The server is connected via a router, the connection to the router is via DHCP.
Currently I'm assigning an address IP for the virtual machine like this:

direct -> eno1 - router network from the physical port.
network -> default - network for virtual machines.
How can I get only 192.168.3.250 instead of 192.168.3.47 (the address received via DHCP through the "eno1" interface, i.e. virtual machine -> physical port bridge)?
