Default Network interfering

Hello, i have an issue where the network created by a compose build is interfering with connections to one of our servers. Im not defining a network in my compose yml, and the build is creating a network with the below config

“Scope”: “local”,
“Driver”: “bridge”,
“IPAM”: {
“Driver”: “default”,
“Options”: null,
“Config”: [
{
“Subnet”: “172.18.0.0/16”,
“Gateway”: “172.18.0.1/16”
}
]
},

how do i change this to not use this gateway please? ive been unable to get the correct syntax for defining my own network in the compose yml.

any help appreciated!
Thanks!

please ignore this request… i have found the solution

networks:
mynetwork:
ipam:
driver: default
config:
- subnet: 172.28.0.0/16
ip_range: 172.28.5.0/24
gateway: 172.28.5.254
