I noticed during the stream one of the astronauts selecting some input on his screen, pausing for a moment, and then pressing the physical button below the screen to confirm the input. So that's probably their defense against misclicks: any action other than just changing the display mode or opening a checklist has to be confirmed through the physical "Execute" button (there seems to be two of them, one for each astronaut).
