rename wordpress wp-includes folder in directory [duplicate]

The name of wp-includes folder is hardcoded in multiple places on WordPress core, as well as WPINC constant which isn’t conditional and can’t be changed.

Renaming it would take creating and maintaining a fork of WordPress core, which is impractical.

Your best bet is just keeping it out of front end, for example by redefining any assets loaded from it to different URLs.
