How do I move the CR Touch mount position for a "0mm Y offset"?

I have the Ender 5 S1 and Sonic Pad. A YouTube video suggests, among other upgrades, to move the CR Touch to a different position on the print assembly and then modify some code to make it a “0mm Y offset”. The video does not show how to do any of this, unfortunately. Has anyone done this or knows step-by-step how to do it?
