I found solution here:

How can I remove empty xmlns attribute from node created by XElement

var element = new XElement(ns   "urlset");
        element.Add(new XElement(ns   "url",

              //Root Element
              new XElement(ns   "loc", "https://test.com/"),
              new XElement(ns   "lastmod", String.Format("{0:yyyy-MM-dd}", DateTime.Now)),
              new XElement(ns   "priority", "1.0"))
          );
