"Automatic Leading Edge Flap Retraction
Group A leading edge flaps are automatically retracted during ground
reverse thrust operation in order to improve structural life of the flap
panels. The function is armed when the airplane is on the ground and
the flaps are operating in the pneumatic mode.
Group A leading edge flaps retract when armed and engines 1 and 4
are placed in reverse thrust or engines 2 and 3 are placed in reverse
thrust. The flaps re-extended when the reverse thrust signals are
removed. "
Since it says the automatic retraction is only armed when the flaps are driven pneumatically and secondary mode uses electric motors, I'd say no.
I don't see any limitation on the use of reverse in any of the ORH flap checklists.
