I'm not sure I understand what you're asking for. Using a simple example:

services:
  test:
    image: alpine
    networks:
      - test

networks:
  test: {}

I can get container's eth0 to be attached to the expected network:

$ docker compose run test ifconfig
eth0      Link encap:Ethernet  HWaddr 02:42:AC:18:00:02  
          inet addr:172.24.0.2  Bcast:172.24.255.255  Mask:255.255.0.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:260 (260.0 B)  TX bytes:0 (0.0 B)

I also wonder, considering your example as a full deploy section: do you user docker compose or docker swarm ?

yes, I use docker swarm , the below is ifconfig output, the eth0 connects to the ingress network , I want eth0 to use a custom overlay network (my_overall) as the default for eth0 instead of the ingress network
