In 2016, Apple began introducing an auto-power-on feature to MacBooks, which would activate when the user opened the lid or plugged in a USB-C power source while the lid was open. This was seen as a convenience for users who did not want to have to press the power button, especially in the case of a damaged button.
According to The Verge , in case users do not want the MacBook to automatically turn on when opening the lid or plugging in the charger, Apple has provided instructions to turn off this feature with the following command lines.
How to turn off auto-restart for MacBook running Apple Silicon chip
First, the user needs to log in with an administrator account, open Terminal from the Applications > Utilities folder, enter one of the following commands

Disable autostart only when lid is opened: sudo nvram BootPreference=%01
Disable autostart only when plugged in: sudo nvram BootPreference=%02
Enter the administrator password when prompted (the password will not display as you type), then press Return.
The above command will help turn off the MacBook's auto-start feature when the lid is opened.
If you want to re-enable autostart, use the following command in Terminal: sudo nvram -d BootPreference
