Disable app library screen

I have apps on my iPad I don't want my kids seeing (games that I don't want them opening and ruining my progress). I have done several things for these apps: - Hide from search - Disable notifications - Bury deep in folders But then Apple released iOS 15 and _boom_ suddenly all they need to do is swipe right and there they are! The apps I totally do not want front-and-center are now exactly that. Is it possible to disable App Library? I suspect no. Is it possible to remove apps from the App Library? I suspect no. Is it possible to passcode lock some apps? I suspect no. Currently whenever I hand them the iPad I specifically put it on an app and turn on guided access. But it would be nice to give them a little more liberty without giving them basically everything. Any ideas?
