How to automatically block users by IP in Nginx?

Question

Nginx

How do I configure nginx, or put something in front of it, to block IP addresses that have more than a certain number of visits to the site?
For almost a week someone has been shitting on one of my sites. Moreover, if it were just parsing, I wouldn’t bother, but here they come from the browser (I assume that they use selenium or phantom), wait 1-2 seconds, or don’t wait at all and close the page. The metric sees this and fixes it, and accordingly, behavioral factors worsen. In Metrica, this is reflected as a surge in direct visits to the site.
Now I put https://goaccess.io/,cool thing for analyzing logs, with the help of this tool I do this: I see an abnormal number of requests from some ip and block it in Nginx. Here, we need a tool that would do this automatically. I'm sure there is one.
