The opposite of "more discoverable" can be "less visible", "hidden", or "obscure". When something is less discoverable, it means that it is not easy to find or locate. It might be inaccessible, or the search process might require extra effort or assistance. Conversely, when something is more discoverable, it is more likely to be found quickly and easily. This can be applied to anything from websites and apps to physical objects and locations. The goal of many businesses and organizations is to make their offerings as discoverable as possible, but sometimes they may want to keep things more exclusive or private, resulting in less discoverability.
