While this is not something that can be done through our control panel, it can be accomplished by using the built-in functionality of NGINX or using mod_ratelimit on Apache.

Apache

NGINX

Additionally, there are third-party services, such as CloudFlare, which can provide more advanced options.

I’m new and not 100% familiar with what you’re looking for but I limit my ssh and a few other ports with the limit option in the firewall.

Example if I wanted to limit standard ssh I would do it like this:

sudo ufw limit ssh/tcp

or

sudo ufw limit 22/tcp

Both will limit port 22.

It’s not to directly block but incremental temporary block.
