It is a setting in a browser. In the early 2000s the browsers even came with their own built-in popups asking if you want to accept cookies from this domain. Of course this was annoying so everyone had it set to "accept all", which then became the default and eventually disappeared.
20 years later, some moron lawyer reinvented the same but worse.
Honestly that fucking box everywhere is worse. It should be a God damn setting in the browser not per page shit.
There are a few extensions that try to automatically handle different cookie popups with your pre-selected preferences. Consent-O-Matic is one.
