It’s a little different with electronic smart switches. Because what we offer here is to disable manual control on demand which leaves the existing wiring as is (you won’t connect load to line directly as shown in the installation above). As opposed to mechanical switches which physically control the relay with the toggle or paddles, Z-Wave switches use buttons to activate it (buttons are pressed when you press the paddle or toggle up the toggle) and these buttons can be used in many different ways including remote control. So it’s not like you’re actually disabling the relay and if you need to cut the power off to the bulbs, you’ll need to make changes to the wiring again or open the box up.
Additionally, you have an air gap switch by the dimmers that can cut power to load even if manual control on the paddles is disabled. That would typically be enough to comply with most regulations but as @JDRoberts said, it’s always good to check your local requirements and maybe consult an electrician before bypassing wall switches.
