How to trigger relay/mosfet board with gcode (5v pins)

(assume I know nothing about the duet) I want to trigger a 5v mosfet/relay board with a gcode command (just on/off no PWM) to control LED strips with gcode or other devices. How would I do this? Is it possible? And can it be on 2-3 pins?
The signals provided by the Duet are 3.3V. Depending on your relay board, a 3.3V input signal may be enough to trigger it. The relay board will need 5V power, which you can get from either the expansion connector or from the PanelDue port.
