Firstly before answering your question, you will be delighted to know that for 2022 JEE advanced there's no 75% criteria. In brochure it was just mentioned that you need to just PASS the class XII, so you can stop worrying about it and continue your preparation.
Now, coming to your exact question, so yes, you can choose another language subject as your fifth subject besides PCM and English and JEE advanced brochure 2022 clearly mentioned subject other than above four.
Hope this helps!
Good luck for your preparation and exam!
