Can servers in load balancer has it own tls certs

now I have several servers in load banlance,and each server need mTLS,so each server has different tls client certs, now I add certs in serversTransport like this, serversTransports: { myTransport: { certificates: [ { certFile: "/certs/server1/client.cert", keyFile: "/certs/server1/client.priv" }, { certFile: "/certs/server2/client.cert", keyFile: "/certs/server2/client.priv" } ], insecureSkipVerify: true, rootCAs: [ "/certs/server1/ca.cert", "/certs/server2/ca.cert" ] } }, and only one succeed in redirect, how can I specify certficate for every server,
