Uninstall all mods with the mod manager you installed them with. Don't forget to hit the 'save load order to file' button. Keep in mind that some mods may require extra steps such as doing a long rest and save before uninstalling. Always double-check the mod's uninstall instructions.
Any mods, e.g. Native Camera Tweaks, that are dropped into the \bin folder read the uninstall instructions.
