How to ‘hide’ a new language until complete

Hi, please can you give me some advice ? I have built a dual-language site using your stunning plugin, it really is excellent. I use the language-switcher to change between the two. I now want to add a third language, but want to ‘hide’ it from the public until I have built all 170 pages in the third language. My question is : is it possible to enable the third language (so that I can build the pages) but hide it in the language switcher until I have built all the pages ? Thanks – all suggestions welcome
