[2022] Is unbanning possible?

Hello there traveler! I am in quite the complicated situation. Long story short. I was gone outside my city for studies and let my gaming laptop at home so i can focus on school. My little brother tried out for honor. He was bad at it, he tried cheating. He got banned. He didnt tell me. He tried to mask every evidence of it. And now about 1 or 2 years have passed since I was banned and didnt knew about it. No, I didnt play for honor in a long time because of work and studies(and I was in a different city). Just found out I was banned and searched throughly through my e-mail to find that my account was permanently suspended. My question is, can my account be unsuspended? I got about 300 hours of legit playing and it seems unfair to get permanently suspended because my brother is a sore looser. I really dont want to loose my centurion main which I invested so much time in it... if its possible please help..
