This mod is fully configurable. You will find the config files in your config folder, a quick way to get there is by opening the Resource Pack menu, open the folder, then go up a level and you will see a config folder. In general, most mods will place their config files there.
This mod has keybindings to disable switching on the fly, you will find them in the options menu with all the other keybindings.
