Hi, Maybe I can answer this or help you answer it. This plugin uses the recommended WordPress Codex solution to the time out problem. It automatically writes the code to your .htaccess file so you don’t have to dig around and spend longer on trying to solve the problem that it’s worth. We have all been there.
Thus, if nginx accepts the .htaccess code and acts on it, then yes. It will work for nginx.

Thank you,
