unfortunately no, pronouns are kind of a specific thing that people use in conversation, and they’ll just guess if you don’t give an answer. Any sort of joke will always show that you’ve seriously thought about pronouns a lot, as well as invite a followup to ask what your actual ones are. I don’t think anyone asking in person is going to be weird to you if you just say “any” though, and leaving stuff blank on forms sounds fine if it doesn’t make you fill it in
