How to disable loading css joomla?

Question

Joomla

Good afternoon, Please tell me:
When loading the page, it connects

/components/com_virtuemart/assets/css/facebox.css?vmver=94fa8a5a

No way I can turn it off.
I tried adding to the index of the template:

unset($this->_styles['/components/com_virtuemart/assets/css/facebox.css?vmver=94fa8a5a']);

won't turn off.
The JSCSS Manipulate plugin also fails

Answer 1

1. Rename the facebox.css file, for example, to facebox-OFF.css
2. Take a closer look at the template code, you can usually see everything without unset
