One of my favorite quotes, no idea about the author or the date, is "discoveries are made by not following instructions". Laughing because you're trying to get more from a machine that is built to give less would be really stupid; that is actually clever and admirable, and when one succeeds it gives extreme satisfaction. As for Nvidia drivers I can't help because my last experience with their cards is quite old, possibly older than the Nouveau drivers, but keep trying; it couldn't be a Alpine Linux failure as Nvidia, according to a famous Linus Torvalds quote, has already been less than friendly to Linux developers in the past.
