Hi Dave,
No, unfortunately we don't have anything like that. Basically the reason is that OSA is super flexible and there's really a lot of ways on how to configure networking, depending on workload.
Not saying that some ppl would leverage bare metal provisioning systems, like Maas or Ironic, which would configure networking their own way.
However we have a role that is super helpful if you want to configure networking with systemd-networkd. We use that role in CI and have some example on it's usage here:
So depending on your workload you just need to have a sample playbook and vars defined for hosts
