On Xbox One you can unlock a card by holding down the Y button on your turn.
haha... hilarious.
thereisnobuddha ignore that, holding down Y on xbox passes the round.
As to your original question buddha.
As of right now there is no way to unlock a card without returning it to your hand, or killing it.
this 'may' change in the future, I say 'may' because i don't know if CDPR want unlocking to be feature, its possible that the current cards that lock, cleaver auckes, ithlinne, will in the future act as a toggle, but i don't know if that will be the case.
