Sources on Internet claim under Settings->Display there's a setting to turn off "Taskbar". It's not present on my system. So I think: Maybe I can just remove all the items from the bar. I find settings for "show recent apps in taskbar" and "recommended apps in taskbar". I disable them. That leaves only the "quick launch" bar from the home screen. I try removing all the icons from that.
*The quick launch bar, and the "taskbar", grow a noninteractive gray square in the space where apps would go*
