Heres' how I make a Macbook stop turning on automatically. Mine is from 2018 and has the touchbar but I hear it works for 2016+ models. This will prevent a Macbook from turning on automatically when the power is plugged in or when the lid is raised; the feature is called "Autoboot". I have also included the command to turn Autoboot back on again if you decide you don't like it off. This setting also makes it so the startup chime works again.
# Turns off autoboot. sudo nvram AutoBoot=%00 # Turns on autoboot. sudo nvram AutoBoot=%03
