Penta SATA HAT for Rock Pi 4 LED control

Dear all,

is there a way to control / switch off or at least dim the blue LEDs on the Penta SATA HAT for Rock Pi 4? I tried to follow the guide on LEDs:

https://wiki.radxa.com/Rock/LED

I looked even on GPIO and hat wiki page:

https://wiki.radxa.com/Penta_SATA_HAT

But no information foud for penta hat LEDs. I also tried to do file system search for “led” or even “trigger” but nothing.

Thank you in advance for your reply
