Little help finishing setting up please.

[Mojo24]

Set up is:
9800x3d,
Gigabyte b650e Aorus Elite X AX Ice
Corsair Vengeance RGB Expo 32GB DDR5 48000 C30 MHz6000
Montech Sky Two
I’m at the stage where Windows 11 pro, all drivers ect are updated. But noticed last night there is a bios update available which I have not done as everything works or sort of and was in the middle of setting it up. The current bios version I have is F32f.
So my plan is to enable Expo save settings exit and restart pc. There is a slight sync issue with the case argb lights and cpu argb/ram rgb. But according to google holding the led button on the case for 3 seconds will let the MB sync everything?
Was thinking of undervolting cpu only very slightly. How do you do that? Or do you think I should just leave it alone and be grateful it works? After finishing the above should I update the bios?
Is there anything else I should do? Is there any recommendation for software to download? This is only going to be used as a gaming pc. Any advice would greatly appreciated.
P.s. Anyone have any experience of assembling Dream House Barbie as that’s my main job tonight.

Updated BIOS have updates for that CPU so I'd do it. "Update AMD AGESA 1.2.0.2a for Ryzen 9000 X3D CPU performance optimized"

Recommend doing the bios updates.

Make the system much more stable.

I used to have regular issues but keeping the bios updated has eliminated it being unstable

My case is a Montech Sky Two, has 4 argb, pmw fans. 1 rear, 2 side and 1 bottom. When I shut down the pc the bottom argb light stays on. Any ideas how to solve this please?
