To be clear, in an acidic solution, because the rate of hydrolysis of sugars is greatly increased! So the catalyst is not sulfuric acid, but hydrogen ions! You can add any acid, but you also have to take into account that the acid roots may interfere with the hydrolysis of the sugars, so sulfuric acid is usually used!

Maltose is a sugar, hydrolysis occurs only with water, adding enzymes, acids or bases just speeds up the rate of hydrolysis!

So if you don't want to wait, add enzymes, sulfuric acid or sodium hydroxide, it's fine if you don't, it's just extremely slow!
