I will derail minorly and say you may be mixing up cliches vs. conventions, and turn it into another piece of advice
Clichés are overdone methods of delivering conventions
For example in the most ham-fisted way possible - your vampire novel is not cliche if it includes vampires, your vampire novel is cliche if your vampire is pale as snow, suave, charming, has a penchant for black clothing, and sleeps in a coffin (and hey, even that doesn't nail it as a cliche if you do something different with it).
More nuanced, I'm going to explain with romance because I'm writing this rn and I know more cliches. A romance convention is that scene where the characters sacrifice something to affirm their transition into the 'improved' self that's compatible with the other person, leading to the happily ever after. A cliche version of this is the man running through the airport to catch the woman just before she gets on the plane, confessing his love (hopefully sacrificing something) and she throws away her dashing career hopes and doesn't get on the plane. Happily ever after
Non-cliche ... well, the sky's your limit, but the beat must still be there. If the woman gets on the plane anyway ... well, that's the story of her putting herself before everyone telling her she needs a man to be happy, not the story of her romance. If it were a romance, the man would get on the plane with her, happily ever after (and there's your subversion).
Romance readers need to see the characters take the last leap into being right for each other and completing their character arc, else you've written a tragedy or a drama or a coming of age or something that isn't a romance, no matter the romantic elements.
