FWIW, if you created the connection between GitLab and GitHub for your project before 10.6, you'll have to remove the connection and then re-add it to get the push-based mirroring to happen. Otherwise, yes, it will still poll.

How do you do this?

It seems like you should be able to do this, but there may need to be an update to work with already-mirrored repos since the feature was designed to have a flow that expects a new project to be created.

I've logged an issue to track down the process: https://gitlab.com/gitlab-org/gitlab-ce/issues/44552
