Is 'Cleaning' Your Transcripts Allowed?

I don’t want to add courses or change my grades. I’m content with my GPA. I just don’t like that I took so many unnecessary courses. I was going to ask my counselor about it, but I wanted to know if the question was silly or not before I did. Anyway, I don’t see how it’s unethical. Plenty of students participate in clubs, but then upon deciding that they don’t want to pursue those activities anymore, don’t put the fact they joined in the first place on their application.
