The cookie is a “third party” type.
Opposite to a “first party” cookie, a “third party” cookie couldn’t be block using standard programmatical methods.
The only way to do it is to prevent the script that is adding the cookie from initializing.

How to remove cookies that are generated before plugin is installed?
It’s not always possible to remove existing cookies. For example, “third-party” cookies cannot be removed programmatically. The only way to “block” them is to prevent them from creating.
Users can also remove them manually, by going to the browser settings and clear cookies there (users can also use CTRL + Shift + Delete shortcut to open the browser settings for clear cookies).
