Yii 2. How to change backend and frontend url?

Question

Yii

Deployed Yii 2 with advanced application template.
At the root are two folders frontend and backend.
We configured the root via htaccess to the /frontend/web folder .
It was /frontend/web/index.php/site/index
Became /site/index - ok.
But paths to css files still remain through /frontend/web/css Is it possible to disable /frontend/web/
path generation globally in yyi2 settings (for menu items, scripts, etc.)?
