The whole philosophy of the LP12 is - if I am not mistaken - close mechanical coupling from platter bearing through the tonearm to the stylus (and record groove) while isolating these components from outside vibrations.
It seems to me that un-loading the bearing would be detrimental to that goal.
I never experienced bearing noise (rumble) when I owned an LP12.
