I missed that there was a new kubeadm API, so we have no work on this yet. If you're interested in working on it see the following for the kubeadm templates: https://github.com/kubernetes/minikube/tree/master/pkg/minikube/bootstrapper/bsutil/ktmpl

And where we use the proper template depending on the K8s version in use:
