Question about gnmi_get and Unmarsha JSON_IETF

I am using GetJsonIetfVal()on pb.Update inside a GetRespose.Notification and, I am able to the JSON payload coming back from the node. Is there a method to Unmarshell and assign this payload to YANG go struct (ygot generated bindings)? I am not able to see the go struct getting populated with the JSON data.

For example, gNMI Get for xPath "openconfig-interfaces:interfaces/"

for _, pbNotification := range GetRespose.Notification {
	for _, update := range pbNotification.GetUpdate() {
		InterfaceByteVal := val.GetJsonIetfVal() <<<<<<<<<<<<<

ocInterface := &yangmodels.Interface{} // /openconfig-interfaces/interfaces/interface YANG schema element.

err = json.Unmarshal(InterfaceByteVal, ocInterface)
