Okay, but you can quite literally just delete the cookie banner. Cookie banner forces websites to ask for consent, no cookie banner = no consent = less tracking since they usually hold off on ALL tracking until you interact with the cookie prompt.

I have personally never ever had any problems with the cookie banner since Brave deletes them with 100% accuracy, there's sometimes where a site will refuse to function properly, but it's usually sites I don't care about anyway and if I HAVE to get it working I disable brave shield, turn off all tracking, consent and turn the shields back on.

It is unfortunate that most browsers cannot implement this as it goes against what the companies behind the browsers want. Deleting the cookie prompt would stop people from occasionally just accepting all cookies and opting into tracking after getting tired of it.
