I need to replace my Serpentine belt and i want to bypass AC clutch and compressor

that is something that has to be done at an auto parts store. if clutch will still freewheel no need to do that just disconnect compressor wire.

The clutch completely fell apart in my hand so it is not even on the vehicle. something keeps tearing the belt to shreds which basically just powers the alternator since the compressor pulley will not move at all.

it may have been the compressor pulley, if you have to by pass it then it has to be done at auto parts, hunt and try style as the manufacturers have no listing for this. we see this all the time.
