Post on the music forum. People there can help you as well.
If you apply to programs (like BA or BS) you won’t need to do an audition for admission, most likely. The only question is whether you should submit a music supplement. You don’t need to do trial lessons.
If you apply to a double degree program, you will of course have to audition. There are usually prescreens. If you want that route, you can do a virtual lesson if schools are too far away or COVID is an issue. Find a teacher at a conservatory prep, conservatory or school of music- or in the community if available- who can advise you.
