Check your QRH, under required equipment for CAT2/3.
There is a note near the bottom regarding automatic rollout where 1 of all of the following is required for automatic rollout: BSCU channel, anti-skid, and NWS. Without any one of them autoroll out is not available/to be used, but you can still do CAT 3 single and CAT 2, however your vis minima changes slightly; specifically CAT 3 single your midpoint minimum visibility changes from 75m to 125m.
It is worth noting that the maximum crosswind component with auto rollout is based around using maximum thrust reverse on the most adverse engine during an engine failure scenario. The aircraft in reality is likely very capable during normal low visibility ops able to handle substantially more than the maximum crosswind limitation with auto rollout; therefore it could be argued that it may be pragmatic and reduces workload to keep auto rollout engaged above the maximum wind limitation and monitor it, and then takeover as required. Check FCOM LIM-AFS Automatic Landing for a note that essentially infers this… “provided the wind does not exceed the maximum wind conditions for automatic rollout”.
