Seems reasonable that they have some sort of rules engine that tracks this type of thing. A country banning a particular aircraft might be rare but differing environmental and noise laws around the world probably means there are quite a few restrictions on which aircraft can go to which destinations beyond the major reasons like runway size and gate facilities.

Such a rules engine is required for day-to-day ops management of a heterogeneous fleet (e.g. "list nearest airplanes to airport X that can fly non-stop for Y nautical miles to airport Z". Or "create flight plans ensuring that each airplane is certified in both departure & arrival countries"). I doubt hard-coding would be required, as such a system is likely flexible
