It is the same as the "more apps folder promoted apps issue"
Open the More Apps folder (in your case Giochi?)
Tap on the folder name ‘More Apps’ or whatever you renamed it (tap on the Giochi as seen on the screenhot you provided)
Turn off the Promoted apps switch.
In Unix systems, files have 3 authorizations: read, write, and execute.
(For 3 categories of people: the owner of the file [usually its creator], a group of people, and everyone else, but it is out of the subject).
If you remove the execute authorization of the file, it cannot be launched (executed) anymore.
