Charging battery

Is there any way to turn off charging when using a USB-C connected monitor that provides pass-through power and therefore charging?

Connect the power adapter to the computer first, and the power adapter will be used preferentially.

Some Background:

MacBook Pro use smart charging through USB Power Delivery and negotiates Voltage and Current delivery with smart charging devices.

Simply connecting a power source does NOT automatically charge your computer. the computer commands the entire charging process, and a power supply cannot "force itself" on your computer.
