You can, but you shouldn't. Vercel has a different approach to hosting backend works, and compared to your traditional setup it would be non-performant. I would suggest Heroku, but as the post below states, it is no longer free and may not be suited for you.

This was already answered in another StackOverflow post too, here. I recommend you reading and verifying as I'm newer. It also tells you how to set it up on up-to-date information, if you're still interested.
