I don’t think that exists since Cognac is barrel aged, and it would lose any carbonation from fermenting when it is aging. You can mix it with sparkling water if you really want a “bubbly Cognac” or, if you are into home brewing, you can try to rebottle Cognac with some priming sugar or carbonating drops

You’d have to force carbonate with CO2. 40% ABV is way too high for fermentation.
