Deamon requires restart when configuring docker_daemon_options

When installing docker using this role, setting the docker daemon option "metrics-addr" has no effect until the daemon is manually restarted:

  - name: Install Docker
    ansible.builtin.import_role:
      name: geerlingguy.docker
    vars:
      docker_daemon_options:
        metrics-addr: "0.0.0.0:9323"

$ sudo journalctl -u docker.service -g 'metrics API listening'
-- No entries --
$ sudo systemctl restart docker.service
$ sudo journalctl -u docker.service -g 'metrics API listening'

This is true whether or not this is a completely fresh install of docker.

Am I missing something? Is the intention that docker will use these options when it first starts? And what is the best way to restart the daemon when it is already running when this role changes the options?
