Hissing Noise from USB ouput of Intel NUC

I have a quick check on my Intel NUC 8i5BEH, there’s BIOS update rolled out last year October, do you think I need to update BIOS UEFI ? Not sure will the update reduce the electronic noise a bit?

My Intel NUC is a dedicated 24/7 Roon Core, no other application except streaming music.

When I installed my ROCK in Intel NUC 18 months ago, I have updated BIOS during that time, do I need to update to latest BIOS and follow the following instruction again ?

After reading this Roon Core Machine NUC 8i3 BEH down after Bios Update BE0090.bio

I should skip the BIOS update.
