Yes the bearing cover doesn't preload it itself, it just holds the preload. The same as a stem would on a normal set up. So you are fine to just remove it and swap it for a round one.
I was just going by what I'd seen online including the acros website and the official canyon conversion kit and which includes a new expander and cap but you should be fine using your existing bung assuming you either have it at a suitable depth already or you're able to get it out and refit assuming you want to cut down the steerer.
