Welcome to the forums, @jocalco. Modding games on an Xbox One is impossible, except for games with dedicated mod support (like Fallout 4, Farming Simulator, and Skyrim). I know this as I have an Xbox One, I tried modding KSP, GTA V, and others, and there are systems in place to stop it. It isn't possible, unless the developers release official modding support for Enhanced Edition (which I doubt they will).
IMO I believe that sometimes it's good to have a stock game, and not any mods. I play KSP on PC as well and with so many mods it becomes a nightmare sorting through thousands of parts, the loading times, and crashes associated with it.
Hope this answered your question!
