LightBurn using a SD card

I have a question that I can not seem to find a answer for by reading.
Can I save a LightBurn file saved out in Gcode to an SD card then just use that card to run my laser or do I have to have the my computer plugged into my laser to run my file from LIghtBurn. I am converting my old 3d printer into a laser engraver using Marlin laser software and would like to keep my computer free.

Yup. Just disable beginner mode first:

Then choose “Save GCode” on the laser panel:
