How to create macvlan with IPv6 support

Is there a solution to create a macvlan wtih IPv6 support in OMV7?

I am running Technitium-DNS as a local DNS server, but it currently only supports IPv4.

In OMV the tool for creating networks inside Docker Compose looks like this:

No option for IPv6?

Thank you for any help.

Thanks raulfg3. This is a first step. I added the lines

networks:
  <myvlan>:
    enable_ipv6: true
    ipam:
      config:
        - subnet: <mysubnet>

in the compose file for technitium. But I have to improve my knowledge about IPv6, I guess. I don't know if and which IPv6 address the technitium docker image has. I have to enter that address in the configuration of my router in order to broadcast it to all clients in the LAN. Maybe I have to set a fixed IPv6 address also in the compose file. All of that is of course not an OMV issue. So, I have to see if I can find a solution.
