Make Lightburn write G01 instead of G00

There’s no current method for excluding G0 moves for rapid movements in LightBurn. However, rapids in GRBL use the maximum speed defined in the GRBL settings. You can reduce those to reduce rapid speeds. $110-112 for X,Y,Z speed and $120-122 for X,Y,Z acceleration.

Alternatively, if it’s only travel between scanning areas that you want to change you could enable “Fast whitespace scan” in Edit->Device Settings and change the speed there.
