Thanks for writing in! This is possible with some custom development, but it would be outside the scope of our support.
However I can point you to the right direction. First you need to setup a child theme (https://theme.co/apex/forum/t/setup-how-to-setup-child-themes/57) and then you can copy the file _brand.php under (x\framework\legacy\cranium\headers\views\global) into your child theme (x-child\framework\legacy\cranium\headers\views\global_brand.php).
Then you should be able to set the link by checking the current language.
Hope that helps.
