I used the method from the link below. It requires a 2N3904 transistor. Collector => 5VBase => 10k resistor => Arduino PWM pin Emitter => LCD Pin 15 A button or switch can be connected to a different pin on the Arduino, then used to toggle the brightness. I'm not using a shield, so I cannot speak to the ease of incorporating this. https://forum.arduino.cc/index.php?topic=207772.ms...
