They clearly spent time adding mod support for the game and then just didn't allow you to actually install mods. What's crazy is that the menus are resized for the Switch and include buttons. I can't yet confirm if custom voices work for those amazing mods that include voiced leaders (although I can confirm those leaders' animations do work).

I can confirm that when packed, custom textures, models, animations, and unit noises all work on the Switch version. With sixteen new civilizations, eighteen new leaders, and major enhancements to gameplay such as Great Ages and an active planet where geology and climatology present.
CIVILIZATION VI SWITCH DOWNLOAD FULL
If the assets have not been packed, you will need to load the mod with the SDK and pack it. Sid Meier’s Civilization VI Anthology includes the Sid Meier’s Civilization VI game, six add-on content packs, the expansions Rise and Fall and Gathering Storm, and the full New Frontier Pass. Sid Meier's Civilization VI Expansion Bundle takes the turn-based strategy classic to new heights now for Nintendo Switch, PlayStation 4, and Xbox One. Rename either the windows or macOS folder to NX64 and feel free to delete the other. If the mods contains other assets and they are packed into BLP files, look in the platforms folder. If the mod contains only scripts (LUA) or database transactions (XML and SQL), you are done. Obviously, you do need to load custom firmware for these files to be read at all. Placing them in /DLC on Switch just makes them load without trouble, unlike placing them in /Mods. Now just move mods to that folder like you would into your Mods folder on PC. Their dependencies will be recognized as well, and you even get their descriptions and information. The game will recognize them as mods, not DLC. On your SD card, make the folder: atmosphere/titles/010044500C182000/romfs/DLC/ Using CFW does risk being banned from future eShop use by Nintendo, so be warned.

It doesn't matter if you use the eShop or game cart version. Instructions will assume you're using Atmosphere custom firmware. To port a mod over that has custom textures, models, animations, or sounds, they do need to have their resources packed, just like when porting mods to the MacOS version. The game has the full mod manager from PC and even has warnings telling you to try disabling mods if you screw something up. If you have a hacked Switch running custom firmware, you can use LayeredFS to add mods.
