We want to add following in the cluster yaml. We are at present doing using the rancher UI. Is there a way to do this using cli or automate it?

kube-controller:  
extra\_args:  
cluster-signing-cert-file: “/etc/kubernetes/ssl/kube-ca.pem”  
cluster-signing-key-file: “/etc/kubernetes/ssl/kube-ca-key.pem”
