No, still dual autopilot for the 737 fail operational. The rudder hardover was kinda solved a bit before the introduction of the fail operational system if i remember it correctly and was a different problem alltogether.
The fail operational 737 needed a rudder servo and rudder channel in the FCC which meant new FCCs, the usual fail passive ones do not have any rudder actuation by the autoflight system at all.
However if you have a fail operational one it can degrade to the pail passive mode (LAND2) and still provide rollout (which enables lower limits than usual for CAT IIIa), however that rollout mode of course is then fail passive as well.
