It's in the FCOM PRO-SUP-32: OPERATION WITH NOSEWHEEL STEERING OFFSET
"The tolerance required by maintenance guidelines (± 0.5 ° NWS offset, corresponding to the ± 3 ° rudder trim necessary to taxi straight) remains valid.
Operating the aircraft outside the maintenance tolerance is possible by using the applicable procedure. However, in such cases, the flight crew must accurately and systematically make logbook entries (indicating the rudder trim input value to taxi straight) to ensure that maintenance can take corrective action within the applicable timeframe. When using rudder trim to taxi straight for NWS offset identification, takeoff must only be performed after a rudder trim reset."
