If you compile wine yourself you could do it the same way that Proton does it.

I do not think there is a native way of doing this, as Proton would have surely used it.. But one could elaborate on that patch to maybe make it to something like Dmitry suggests with an option of "-q" or something.

Now, after seeing what precisely you're trying to do, I have to say that my suggestion should not be used in your scenario. Disabling updates is only appropriate for fully initialized prefixes. Perhaps adding new switch '-q[uite]' or '-nobanner' to wineboot would better match your needs.
Yes, correct, this is what I was hoping to find.
