Network isolation with windows containers

we are running some automation tests Nomad by windows docker containers
each job contains 2 tasks - SQL container and tests container.
In order to reach the SQL DB, we are using a hostname (which defined in the task)
But when I’m running more than 1 job it looks like doesn’t work
I tried to use network mode “bridge” but then got an error that says the windows container doesn’t support this mode

Please assist what is the right way to execute such jobs

If I comparing this to docker swarm, so there we are using
driver: overlay
in order to create a separate network, how it’s possible to do the same in Nomad?
