Configure PAM

This is optional, if you use it, put it after your PAM activation/include.

[pam]
# clearance between print area and mesh area in mm, default = 0. 
# positive value = mesh area will be bigger then the print area
# negative value = mesh area will be smaller then the print area
offset: 10

Make sure this is the first line in your Start Gcode section.

Use minimum SuperSlicer Version 2.3.57.10, earlier versions can report negative first layer coordinates.
