Redirecting Kubectl and Kubeadm to new Load Balancer address

Thanks for reading. I created a cluster with Kubeadm and now I want to add a load balancer for the master API servers. The initial kubeadm init command I used did not use the advertise-address flag. Can I modify the cluster to use one without re-initializing it? The address would be the front-end address on the load balancer.

Can simply change the address in the .kube/config file on the Master nodes?

Thanks for your time.
