2. Cut the VR_READY trace
Pin 3 of the Onsemi NCP81174 is the VR_READY input which will check if all VRMs are working or not. Simply cut the trace at the marked spot to disable the monitoring. The trace is really small so take a sharp knife and be careful not to cut too deep or anything else. If you can’t cut the trace or if you cut too much you can simply remove the whole IC.
