Those clutch paddles are only used when you need to have the car in gear at standstill to start without spinning the wheels e.g. at race start, pitstops etc. They are not used during the course of a normal lap. And it was exactly the same a few years ago when these sequential gearboxes were non-seamless.

turn or change predefined engine maps in ECU of the car by turning down the rpm
or turning down the cylinders ???
Not sure if anyone outside McLaren actually knows exactly what they do, but I assume they might switch engine maps as you just mentioned.
Also they may be some controls that were taken off the steering wheel to improve ergonomics, that were the problem with Maccas recently. Just a thought. Oh, and those could change FM radio stations as well. As I said earlier, Lewis was probably busy doing just that exiting the pitlane at Montreal
