How to change the header and footer in the Section Breaks Next Page using OpenXML?

Question

I have a word document file in which I added a Section Break of Next Page, now I want to change the header and footer of that page.
Scenario of example, I have a doc file which has four pages with headers and footers and added fifth page in the section break next page, I want to change the header and footer of the fifth page only. This is achievable manually by deselecting the Link to Previous
button in the Word Application but I don't know how to change it using XML?
My code that adds the new page in the section breaks is:
class Program
static void Main(string[] args)
string path = @"C:\Riyaz\sample.docx";
string strtxt = "Hello This is done by programmatically";
OpenAndAddTextToWordDocument(path,strtxt);
public static void OpenAndAddTextToWordDocument(string filepath, string txt)
using (DocX document = DocX.Load(@"C:\Riyaz\sample.docx"))
document.InsertSectionPageBreak();
Paragraph p1 = document.InsertParagraph();
p1.Append("This is new section");
document.Save();
Please help.
