The 580 legacy driver is DKMS, so there shouldn’t be any maintenance beyond what is already required for any other DKMS driver, which would be handled by pacman anyways. So no need to worry about kernel updates
If you’re adamant on keeping those GPUs, Nouveau would be the only path forward - eventually paired with NVK for Vulkan acceleration once that’s good enough for primetime. Pascal was dropped because of the lack of a GSP module as well as age, so the newer Nova driver won’t support it either
