I've done the song and dance previously - I kept getting caught out
when the akmod-nvidia was a day or two behind kernel updates!

I think you are thinking of kmod.

If you run with akmod it will automatically rebuild the kmods for you so you won't be caught.  The only "downside" is that now with dnf you have to remember that the rebuild process runs after, and silently, the dnf updates are completed.  If you reboot too quickly the process wouldn't have enough time to finish and when your reboot you'll have a blank screen for a few minutes while it is rebuilding again....silently.  So, if you forget that you may be inclined to think you've got a hung system....but you don't.
