GPIO (leds) default values

I have not found any setting in the UEFI to set the default value of LED 2 and 3 to off.

How can it be done?

Thank you

thank you Tamir, we are already using the gpio to control the LEDs.
However my question was related to the default value of the LED, the one set, I guess, by the firmware.

The LEDs, after power on, are ON by default and we would like to have them OFF.

Unfortunately, it is not possible to control the default behavior from EFI.
This requires certain BIOS development as this feature is currently not available.

As a personal consideration, I think the default value should always be off.
If LEDs 2 and 3 are meant to be customized by the user, they are meant to go on whenever the user service is "ready/on/available" and that happens under some explicit actions; it does not happen when the board is booting.

After my RMA, these LED behave a little differently.
Previously, I could with a simple script (Linux) turn off the LED directly at startup, if I wanted.
These LED then remained off even at shutdown.
Now these LED are lit green which feels illogical. Yellow or off when the unit is off would have been more logical.

Can you please check the BIOS version of this device?

R&D did a roll back of BIOS, so you can try to install a new version.
