Change 302 locale redirects to 301 redirects

Thank you for your response. Can you also tell me what happens to the 302 if I want to do it the other way around, so a 301 redirect for / to /en? Does the 302 from the localization auto-routing still exist afterwards? I’m afraid that this could be the case and that there could be conflicts. As far as I know it is not possible to remove this single 302, right?
