A workforce agreement to relax the 10 hour night work rule applies to all workers at that location who do the same type of work. Your being an agency driver rather than directly employed has no bearing on it.
Also note that it’s not something you can opt in/out of on an individual basis. If there is such an agreement in place there, the 10 hour limit doesn’t apply to you.
