Possible to use bike without display?

I have a 2017 Lacuba E8:

is it possible to get assist without the display? I'm just wondering what happens if I lose/drop the display, or when it eventually breaks one day.

My only experience with no display was with a Sondors. Came from the factory that way, and the controller had a default of something like PAS1. But it also had a throttle that ran at full power, so the bike was rideable. No throttle and it would have been a stone.
Generally the switch for up and down is just that, a switch. The display "communicates" with the controller. Without a display you may have a controller default, maybe not. No idea how Brose handles it.
