how pass X509Certificate2 to potocol gateway about azure-iot-protocol-gateway HOT 2 OPEN

i can pass certificate by willmessage in connectpacket, but i don't like this approch, anything else?
code as followed:

var x509Certificate = new X509Certificate2(@"E:\LLNC1AAA0EA001030.cer");
var buf = x509Certificate.GetRawCertData();
var setting = new MqttTransportSettings(TransportType.Mqtt_Tcp_Only);
setting.RemoteCertificateValidationCallback += (sender, cert, chain, error) => { return true; };
setting.HasWill = true;
setting.WillMessage = new WillMessage(QualityOfService.AtMostOnce, new Message(buf));

there's no good way to pass-through client certificate. Either use Hub-scoped credentials on the way to backend or if you can, store client certs locally on PG nodes for lookup/pull for forwarding.
