On Brave desktop, I can’t find a way to disable the tip icons/buttons that get injected into websites. I searched around for a way to do it, and various forums posts say to go to the “Rewards” section in settings and disable it there. However, there are no options in that section for disabling this feature. I think the software may have changed since those forum posts, and the method might be different now, or require doing some other action first.
I’m posting a screenshot of the “Rewards” section in settings. This is with the latest stable version of Brave: Version 1.21.73 Chromium: 89.0.4389.72 (Official Build) (x86_64)
