is it possible to block a specific cookie from being setup using javascript?

Question

I am working on a Wordpress website to make it GDPR cookie law compliance. So I am wondering if it is possible to block a specific cookie from being setup using javascript?

Let's say I have a cookie named as "_example". I need to block this from being set up. How can I do this?

I guess this is what you are looking for: https://superuser.com/questions/709281/how-to-block-a-specific-cookie-from-a-specific-site

By default, browsers don't allow such a fine-grained control over cookies: usually you can either block all third-party cookies or block all cookies for a given domain.
