Unfortunately, you can't. Unfortunately, it does not have a power off/on mode so that it starts up again on its own after a power failure. And firmware updates always fail, so I can't say whether newer firmwares might be able to do this.

And beware when using Fritz!Box with Swisscom with 5G. The Fritz!Box is the better product, unfortunately didn't work for me with Swisscom. Only used 4G and no 5G. Even with Swisscom support, AVM support and replacement device: Nothing to do. Then I got the Predator. Can do less, but at least has 5G - which is the main feature of a 5G router ;)

Buy the Fritz 6850G router, it's possible there. The Predator can do almost nothing.
