Change Promoted State value

The Promoted State column in the Site Pages library is read-only and it is designed to be set by the system. It is not recommended to manually change the value of the Promoted State column, as this could have unintended consequences.

There is no built-in way to change the Promoted State value without using Power Automate or PowerShell. You could use Power Automate to automate the change of the Promoted State value, or use PowerShell to update the value programmatically.

If you do not want to use Power Automate or PowerShell, you could consider creating a new page and copying the content from the News page to the new page. You can then delete the News page if needed.
