Adding a css/js file is easy in a template. Is there a way to remove css files. I am making a user preference that requires adding css if the option is true, but what if I want to remove that css file when the option is false.

This is how to add:

<xpath expr="//html/head/t" position="after">
    <link t-if="option == true" href="option.css" rel="stylesheet"/>
</xpath>
