As I've said elsewhere, you can go to Settings -> Apps -> All -> Discovery Service and disable it. (while you're there, you might want to disable KoboTracking [seriously, guys, why do you hate your customers so much? :/] and the app with the Chinese character name (which is supposedly the IME for entering Asian characters, but which for some reason demands access to your personal information!)
Disabling the Discovery Service will leave the Discover bar there, but it won't be populated with pictures and advertisements.
