The most they could do is not use their titles in everyday life. They can't stop being princesses, because they're the daughters of a prince. They could move to the 'back of beyond', where no-one knew where they were, never tell anyone who they were, and they'd still be princesses.
Beatrice is only a princess because it was George V's royal will and pleasure that she, and others meeting the requirements set out in the 1917 Letters Patent, "shall have and at all times hold and enjoy the style title or attribute of Royal Highness with their titular dignity of Prince or Princess prefixed to their respective Christian names". The royal style and title is treated as part of her identity and her name, however she can renounce her right to that style and title and change her name by deed poll. She would then no longer be a princess. She's unlikely to thumb her nose at her family that way, but I believe she could.
