I have a freshly acquired YK4 Nano, primary use being PIV/SSH, and I'd like to have the LED off except when it's asking for touch to use the key.

Unfortunately, no matter what I do, it blinks every 3 seconds. I've tried setting both config slots to dormant, and generating various credentials in them, to no effect. The documentation suggests that this happens in U2F mode, which I have not configured.

Is there any way to stop this thing blinking? For a device which is permanently attached to my laptop it's not an acceptable behaviour - and if I were to cover it up I'd lose the signing request indicator.

Hello,

Did you tried the inverted LED behavior setting in the settings tab of the YubiKey Personalization GUI?
