If the file has already been uploaded by someone, it cannot be changed in any way. If there is a possibility to connect not only css but also js, then you can sell, for example, a js module that will send a request to your server using the token you provide (which is the same password), but still, even though the file is loaded dynamically, it is still possible to extract data in the developer tools. It is physically impossible to prevent css from being copied.
