Do you mean only on one page specifically?
You could use JS or custom CSS to suppress it.
Afaik, localization doesn’t really work that way. Think of it like “layers” of your site. You choose a locale and then all navigation through the site stays in that locale. Otherwise you’d click a link and then either get a 404 or be forceably locale-switched.
There are exceptions but I’m fairly certain I’ve only seen locale-specific pages in the context of CMS items. Check the docs, they do cover these situations.
