Can I publish a research paper without being enrolled in a university?

No, it can’t be done.

How do I know? Because you haven’t read any journals. How do I know that? Because if you read any journals, you’d already know that the instructions for submissions are printed right in the journal itself. And why does it matter? Because if you haven’t read the journal, you don’t know either if your paper is right for that journal, or if they’re already aware of whatever it is your paper is about.

The bias towards people with degrees and affiliations isn’t some kind self-selecting club. It’s because science is a collaborative process, and collaboration goes both ways. If you’re not listening to what the other people are saying, then you’re not contributing anything new to them. It’s like you’re jumping up and down at the bottom of a mountain, while everybody else is already standing at the top. It doesn’t really matter how high you jump; you’re not reaching any new heights. The people with the degrees get them by demonstrating that they’re climbing that mountain.

All of the other answers are correct: yes, it is possible for a person without those credentials to publish a paper. That’s because you don’t need credentials to read and learn. But if you’re not reading and learning, you’re not going to be able to publish, because there’s an effectively zero percent chance that the publication is going to be of interest to those who are reading.

The way to turn “no” to “yes” is to start reading journal articles. There, you’ll find the instructions to publish. But you’ll also realize just why it takes everybody else so much time and effort before they do.
