How to Remove .php from URL in Webinoly?

Question

Hello, I would like to hide .php and .html from URL for non-wordpress sites. I would like to do it for all the sites on the server, let's say 100, would be a hard task to do it manually for each site separately.

My question is it possible to do it for all sites at once? If yes, how?

Thank you!

I have tried to follow this guide: https://tufora.com/tutorials/linux/general/remove-php-extension-with-nginx

But there is no server block in the conf. file
