Can you apply ceramic coating over ceramic coating?

The answer to this question depends on the context. The answer is probably 'yes', but just because you can, doesn't mean you should.

Some manufacturers recommend two coats on application, which of course is done within a timeframe because of the way ceramic coatings cure.

Should you want to apply additional coatings, it can probably be done, but begs the question of why would you want to? Assuming the coating is working as it should, ceramic coatings by their nature are very thin and there is no real advantage to adding additional coats.

However, like anything else, ceramic coatings will wear down over time. So, as an example, a 5-year coating will have worn down after two and a half years, and although it will still be working as it should, adding another coating before it wears thin, will top it up and extend its life.

If, however, your ceramic coating isn't working as it should, it should be investigated as to why before putting another coating over the top.
