Adding a hot tub after whole house Solar + Powerwalls, don't want it backed up

[kmachine]

We have a Tesla solar + 3 PW system and right now everything in the house is backed up. We had the system put in nearly two years ago so they moved all the circuits from the main panel and a sub panel to feed from a new backup panel. We are now looking to add an electric hot tub 40A 220 but which I don't want backed up. Is it as simple as adding that to the main panel which for now has a single big breaker at the top and no individual circuits?

Hi If the spa has a gecko controller, they sell an inexpensive wifi remote system for it so you can turn it off with the app from anywhere.
