From FCOM 1.7.70
Thrust Reverser System Actuation System
Deployment requires :
One FADEC channel, operating with its associated throttle reverse signal ;
Right and left main gear compressed signals from the corresponding LGCIUs ;
A Thrust Lever Angle (TLA) reverse signal from at least one Spoiler Elevator Computer (SEC).
Before deployment is completed, the FADEC sets reverse idle thrust on the engine that is having its thrust reversed.
So the answer is "No"
