You can use CSS placed in Special:Mypage/global.css to hide the advertised article.

This will remove the Fandom-promoted article, however, this will cause the module to only display four popular pages.

An alternate solution would be to use an ad-blocker extension, which will automatically hide the promoted article and provide you completely with five popular pages.
