Unless u got an actual Vulkan issue, you shouldn't bother to use those: https://devtalk.nvidia.com/default/topic/1035845/is-vulkan-396-24-02-gt-396-24-/
And really, it's as simple as changing the link, the pkgver, and building with --skipinteg (entire build is the same). I don't know why you need a pre done PKGBUILD for that.
