One sure-fire way of getting rid of the whine...

Remove the alternator. With the room under-hood gained by the alternator removal, you could put in a larger or perhaps additional battery.

I wouldn't recommend taking any long trips with this setup, and probably you shouldn't drive at night where use of the headlights is required.

But, no alternator whine. Just be sure to plug in the battery charger every night when you get home.
