How to enable Galera Arbitrator with k8s operator ?

I looking for attaching a Galera arbitrator node with my 2-node pxc step on k8s cluster, I went through steps https://www.percona.com/doc/percona-xtradb-cluster/LATEST/howtos/garbd_howto.html but wondering whenever pod will crash will have to install percona-xtradb-cluster-garbd on the node manually? 

Galera Arbitrator is not supported in our Operator at the moment.
