2019 Pilot Best Practices

Hey all, my wife recently bought a used (Honda certified) 2019 Honda Pilot EX-L with 26k miles on it. This is the first vehicle we’ve owned with direct injection or Honda’s VCM. I have two questions:

* Should I install a device to defeat the VCM system, or has Honda refined it enough that it won’t lead to problems down the road?
* What should I do to stay on top of carbon build-up on the intake valves due to the direct injection?

Thanks!
