Programmatic control of XML Namespace in SOAP response

Currently, I am using the following to set it statically, see below. Based on conditions I’d like to set the namespace in the SOAP method call. How do I have programmatic control of XML Namespace in SOAP response, please?

public static class ServiceNamespace
{
  public const string Empty = "";
  public const string Value = "http://schemas.company.com/api/v1.0/";
}

[ServiceContract(Namespace = ServiceNamespace.Value)]
public interface ISoapService
{
  [OperationContract(Action = ServiceNamespace.Value + nameof(SoapMethod), ReplyAction = "*")]
  [XmlSerializerFormat(SupportFaults = true)]
  [FaultContract(typeof(Status))]
  SoapMethodResponse SoapMethod(SoapMethodRequest request);

  . . . 
}
