How to control Computer RGB LEDs in Linux [closed]

Question

Since I switched to a new AMD Ryzen system my computer lit up.
All new hardware components seem nowadays to have such fancy(?) RGB-LEDs built-in (even in memory modules, even the stock CPU-cooler from AMD).

Is there a way to switch all LEDs in my system off.

The BIOS settings don't offer any control over the LEDs.

Only the mainboard's manufacturers utility software (all for Windows) seems to be capable of controlling that lightning in my computer case.

Is there a way to control such LEDs through Linux Operating System?

A bit late, but just saw this so...for what it is worth... While most PC mainboard and peripheral manufacturers have created their own proprietary schemes for RGB control via Windows software, some EFI settings allow the mainboard control of them to be turned off. Look into your EFI menus to see if you have that option. I have only Asus mainboards, but they have an option for "stealth" which turns them all off. Otherwise you get that saccharine oscillating rainbow color effect. Good luck.
