Can I set it myself. I don’t find the option in the settings

you can use a positive or negative kerf offset to change where the laser cuts. That function is found in the cut settings editor.

Thank you very much. So this is for adjusting the position of the laser head.

No, I wouldn’t define it that way. Kerfsetting is used to compensate for the diameter of the laser beam. It is not used to move the laser head, but to adjust your design drawing/objects.
Try drawing two simple shapes that should fit together, give them an exaggerated amount of kerf and see how your preview window shows the effect, it works with plus and minus kerf.
