Multiple etcadm nodes tls fail from api-server

[fontexD]

I have a setup with 3 control-planes and 3 etcd nodes created with etcdadm

the issue is it generates different api-server-etcd-client.crt so i have 3 etcd-api server certs

but on the api-servers in k8s i can only define 1, so 2 of the nodes will get a error with tls of course
how do i come around this issue ? do i need to use a loadblaancer if i want to use mulitple etcd-nodes or ?
id prefer not to
