[x470 Taichi] RGB-Control in BIOS has no effekt?

As i'm not using windows, setting the RGB in BIOS is my only Option. Unfortunately it doesn't work - no matter what i set, the LEDs stay white for the two lower sources and yellow/red for the part at the I/O-Shield (i've read about that issue, as i want to have red illumination, that wouldn't be a problem for me).
Is anyone else experiencing this?

And second question: if i setup a windows-install and use polychrome to set the RGB, will this persist outside of windows?

In the UEFI bios should be able to set/change whatever you want. I know x370 taichi UEFI can.

And yes, it's persistent until next change, be in in windows or uefi.

But I don't know windows setting can be persistent or not, because new reboot will run uefi command first, which I don't know will sync the windows as last command or not.
