That will not change the alignment pattern from square to rectangular, but LightBurn should utilize your camera’s capture area better that way.
Here are some tips on the lens calibration (and alignment) process:
These are the most common reasons for difficulty with camera calibration:

If you do it on the machine, if you have a honeycomb bed, cover it (bedsheet, paper, wood, etc) - the pattern gets misinterpreted as more circles and confuses the software.
