Can a spell be ended before its full duration by the caster?

@JeremyECrawford can a spell be ended before its full duration by the caster or only concentration-based spells can be dismissed this way ?

You can dismiss your spell only if it requires concentration or the spell says you can dismiss it. #DnD https://t.co/bYkFTmdCqH
