|Create separate sections.|
Make the page(s) where you want a number a section on its own. It will still be in sequence in the finished document.
You insert a section break at the end of the page preceding the page where you want the page numbering to start. When you want to stop page numbering, create another section break at the end of the last numbered page in that section..
Remember to enable/insert or not page numbering as appropriate for each section.
