I have similar (but not exactly the same) devices on my Z690 Hero (see image). Maybe that's just because of our board differences. Anyway, all of them use the same drivers - Intel 30.100.2221.20.
That's the same version as the Serial IO drivers on the support pages for my board. So odd. Have you tried installing Intel's Driver and Support Assistant? It might find and install them for you - worth a try if the support page drivers are not installing correctly.
Failing that, have you tried to install the support page's drivers package with admin rights?
I can only add that I have no idea why the BIOS update would have affected this. Strange things can happen!
