Anyone with 737MAX cockpit time?

Overly nerdy question: I'm curious regarding AoA sensor failure, is there an ability to manually source select the AoA, if not, how about the FMC? This might be called master source select, or which side is controlling (captain or first officer).

The AoA failure logic does not allow for manual reversion of the master/monitoring FCC. It still requires cross-checking sides in the event of an AOA DISAGREE annunciation. But since the update, MCAS is disabled in this scenario. As far as the FMC, the relationship between AoA vanes, flight control computers and CMD A/B is not configurable. But the non-failed autopilot channel can be selected.
