table 2 gerber. partner shows all the rest of the aces and we pass

To bid Gerber seems to be the mistake, not to pass after 4nt. As I'm not sure how the code works and why south passed to 4nt:

we should make sure that RKCB or Gerber is bid only if we want to play slam if 0 or 1 aces are missing. One option would be to look forward for all possible answer options to 4c. If no matter what the answer - we stop at 4nt, then 3nt is better than 4nt.

BBA is purely rule-based and does not sample, which allows for extremely high bidding speeds. This hand is close to a slam, but is probably difficult to bid. S sees:

          K98
          AJT
          JT
          AKT98
432                  AJT76
542                  9876
Q62                  97
Q543                 76
          Q5
          KQ3
          AK8543
          J2

Currently, S does not ask the question immediately after 1NT (no explicitly agreed suit) but asks it after 3C.

I am ok with the use of Gerber, but North responds 3 aces, and South only sees 2 :-)

After Gerber you are not allowed to pass a response of 3 aces (If it would be right to pass you should never have used Gerber)

This situation is before ask. You're right, but it seems difficult to implement.
