Is it possible to change input switch hot keys to another in macOS?
In System Preferences > Keyboard > Shortcuts > Input Sources you can select the keyboard shortcut assigned to, e.g., Select the previous input source and then click on, e.g., ^Space to then change it by then typing the keyboard shortcut you want to change it to.
Note to actually click on the keyboard shortcut itself to open up its edit field.
