Can you become a firmware engineer(embedded software engineer) through bootcamp?

Hey everyone I'm trying to find a bootcamp for software developer and i stubbled on to firmware engineer. I got very interested in that topic. I heard that firmware need to know both software and hardware so I was wondering can you still be able to become a firmware engineer without a college degree but by going through a boot camp. If Yes does any one have some good boot camps that they can say postive thing about. Thank you every one!
