[Rock64] How to activate spi device and controll ws2812 leds?

Hi, I'd like to control ws2812 led's via gpio spi.

I'm using this octoprint build by ldiaz: 

 

 

I checked /boot/armbianEnv.txt and there's overlay_prefix=rock64 and after enabling spi via armbian-config also overlays=spi-spidev.

Then I rebooted but ls /dev/spi* shows nothing.

 

Can anyone help?
