Access the Featured page/Frontpage Menu Item
In your Joomla administrator, go Menus >> Main Menu >> Home.
Note: Your featured page / frontpage may vary where it's located depending on your template and how you set it up. For example, it may be in the "Top Menu" rather than the "Main Menu". It will usually however be in your default menu (the one with the star next to it). If you look under the "Menu Item Type" column, it should show "Articles >> Featured Articles" or ""Articles >> Frontpage Articles".
Set the Pagination to Hide.
