With the help of Nvidia support, I found out that disabling nvidia- persistenced makes it possible, now, to switch between Nvidia and AMD drivers (intel prime profile) by using prime-select. But this demands a reboot between each switch. And, after using "prime-select intel", gnome-shell's option to "start a program using the dedicated video adapter" isn't available anymore.
