Please note that if the GE dimmer you have Has an input for neutral it requires it. GE/Jasco Used to make some dimmers (model 45612) that do not have this requirement. These Do work without a neutral, I have some in use. They are picky as to how well they work with certain LED’s, they work best with incandescent bulbs.
This would give you the most options.
You could also go the Smart Bulb route and use a dumb switch gaurd, or a smart button guard.
