Electrical noise on SSD's when C states are enabled (Asus TUF Gaming Z690 D4)

Hello!. Well, it happens what it says in the title. This has been happening since recently (I swear that with the last update 23h2 of Windows 11), or because I now have a 14700Kf (before I had a 12700KF), the thing is that there is something that is happening so that some of my SSD (or all, I have 3 NVME and 2 SATA), put a very annoying electrical noise when I have enabled the C states that did not happen before.

The solution logically is to disable the C states but I don't like that solution, the processor consumes something more and also gets a little bit warmer in idle/navigation.

I tried to set maximum performance mode from power and it doesn't matter, the noise is only removed if I disable C states.

Best regards

EDIT - 

Ok, it seems that disabling "enhanced c-states" is solved and the SSD's do not make noise, and the CPU continues with the other C-states reducing consumption and temps. That is, leaving it like this:

CPU C-states = Enable
Enhanced C-States = Disable

Before I had both things "enable" and that's why the SSD's emitted an electrical noise.
