That kinda drops relay theory off the shelf.
Put a multimeter with extension wire to the circuit and test drive and see if disconnects on full throttle. If so, ECU is OK, and your problem comes from A/C circuit board. That board might be quite expensive: howabout just living with this: tell like microsoft that from now on this is THE feature, not problem?
Where to connect tst probe is good question: i'd think easiest accessible is the single connector in the compressor. Unplug it, insert long wire inside (first bare it ½inch) and plug it back hoping it will be inside and make connection. Then route the wire outside onto pass seat, connect multimeter and tsts drive. Use duct tape.
To tst my AT gearlock, I built extension wire to TCU cable, see
