How To Display the page number in the specific page on the Contract Simplified Terms printout?

Summary:

Hi,

We have a requirements in Contract Simplified Terms to display the page number on the specific page.
On the uploaded template, we have a 2 pages for cover letter which we do not want the page number to display in the pdf.
The requirement is after the cover letter, that's when we want the page number to display and should start in page 3.

What we tried so far is we have edited the RTF template for Contract Simplified Terms but still page number is showing on the cover letter.
