You can try to disable software End-Stops with this gcode:
M211 S0
Be aware though, if you do that, there is nothing preventing your printer from trying to move beyond the hardware limits and possibly destroying itself. You can enable the end-stops again with:
M211 S1
I'm guessing it's about documenting the assembly of safety-critical components. If some part of, let's say an airplane fails because a bolt comes loose, the manufacturer wants to have a paper trail attached to it to prove that this specific bolt was indeed torqued to the correct spec. Connecting the wrench to the network could make this documentation much easier.
