I need to do this to move on in the game, and I am willing to do anything…
But I was wondering, is there any possible way to 'cheat' the game and complete a quest in The Witcher 3: Wild Hunt? I will do anything in order to complete this quest including using other means than completing it legitimately, because I am unable to do so because of a bug. The quest in hand is The Play's The Thing and if you want to read my problem, it is a separate question on this arqade account.
However, a solution for all quests might be more useful for other people with a similar problem.
As I said, any solution will do, whether that means installing a client or modding the game files. I have already tried console commands, but every source I have looked at does not seem to give commands that directly affect quests (e.g. finish.current_quest).

There is no way to do that.
You can try load another save or auto save before you activate that specifc quest.
But the answer in the post that you mentioned is perfectly valid. Didn't work?
