I would expect that you just need to establish a serial connection to it and then send $23=whatever. Any software that sends Gcode can do this, or even just a terminal emulator connected to the serial port, for example 'screen -r <tty>'.

And I'm still trying to offer it. :) My apologies if I am misunderstanding the situation. I think you just need to send the Gcode over the USB port. I expect it only needs to be done once to permanently reconfigure the machine homing. Or ask in some 3D printer forum where folks are familiar with your machine, or search the web for 3D printer homing configuration guidance.
