To achieve this function, first you need to create a class that inherits from XmlSerializerOutputFormatter :

public class XmlSerializerOutputFormatterNamespace : XmlSerializerOutputFormatter
        {
            protected override void Serialize(XmlSerializer xmlSerializer, XmlWriter xmlWriter, object value)
            {
                //applying "empty" namespace will produce no namespaces
                var emptyNamespaces = new XmlSerializerNamespaces();
                emptyNamespaces.Add("", "any-non-empty-string");
                xmlSerializer.Serialize(xmlWriter, value, emptyNamespaces);
            }
        }

Then, add the following service in ConfigureServices in startup.cs:

 services
    .AddMvc(options =>
    {
        options.OutputFormatters.Add(new XmlSerializerOutputFormatterNamespace());
    }).AddXmlSerializerFormatters();

In api method:

   [Produces("application/xml")]
    public IActionResult GetXml(ValidateRequest request)
    {
        ValidateResponse response = new ValidateResponse()
        {
            Amount = 100,
            ClientValidateNo = request.ClientValidateNo,
            Client_Code = request.Client_Code,
            DepositorCity = "aaa",
            DepositorName = "das",
            DepositorState = "sadasd",
            Status = "fasfas"
        };
        return Ok(response);
    }

The test result:
