Hi,
You can turn off Brave Tradutor on brave://settings/languages (also add your preferred languages in the first option on the configuration page) and additionally disable the translation for the entire Spanish (or other) language in the translator icon.
In my example below, I’m disabling the translator so that it no longer translates from English to Portuguese, any site. And it’s working fine.
Do you have these settings and are you still seeing the option to translate?
