Stop dhclient from sending DHCP requests for docker containers - Stack Overflow

I am running a couple of docker containers in a VM (Ubuntu 22.04.05 LTS). In the syslog, I see a lot of DHCPDISCOVER entries:

Feb 25 09:42:01 streamshell-prod dhclient[3528603]: No DHCPOFFERS received.
Feb 25 09:42:01 streamshell-prod dhclient[3528603]: No working leases in persistent database - sleeping.
Feb 25 09:42:01 streamshell-prod dhclient[3528603]: DHCPDISCOVER on veth1a286b1 to 255.255.255.255 port 67 interval 7 (xid=0x8bb16d69)
Feb 25 09:42:02 streamshell-prod dhclient[3528603]: DHCPDISCOVER on docker0 to 255.255.255.255 port 67 interval 9 (xid=0x8b66cb6c)
Feb 25 09:42:03 streamshell-prod dhclient[3528603]: DHCPDISCOVER on veth93bb6c9 to 255.255.255.255 port 67 interval 7 (xid=0xb9c97401)
Feb 25 09:42:03 streamshell-prod dhclient[3528603]: DHCPDISCOVER on vetha80e9f5 to 255.255.255.255 port 67 interval 7 (xid=0x8df0612b)

It seems like dhclient is asking for DHCP addresses for all my docker containers. I think I don't need this (unless it is some docker internal thing required for the containers to talk to each other). My containers are not directly exposed, but talk to a proxy. Is there a way to tell dhclient to stop this, even if it is maybe just a cosmetic issue?

The containers are started using the Python Docker API:

hostname = "mycontainer"
networkname = "mynetwork"
networking_config = client.api.create_networking_config({
    networkname: client.api.create_endpoint_config(
        aliases=[hostname]
    )
})
container = client.containers.run(
    self.docker_image, detach=True, network=settings.STREAMSHELL_DOCKER_NETWORK,
    networking_config=networking_config, hostname=hostname,
    links={hostname: None}, name=hostname)

Output from ip addr:
