Refus d'accès paramètre de la zone de lancement BI

Hello everyone,
I have set up the display of the BI launch pad home page so that only the ‘Category’ and ‘Recycle bin’ mosaics are visible. It works. Except that if the user goes to parameter he can display the other mosaics. Is it possible to block a user’s access to the BI launch zone parameter?
