I don't really know anything about this specifically at this point. (It's been quite a few years now since I was involved with this sort of thing.) But back when I was, if a person did not disclose a disability prior to starting a new job, the employer would not be required to provide reasonable accommodations should they later on be needed.

If there is some sort of governmental employment services office where you live, it might be worth a quick call to them to clarify exactly what the current requirements are. On the other hand, if you're confident you won't need or want any sort of accommodations at some later date, then there may be no reason to disclose & you may be better off just keeping the information to yourself I would think.
