Blue light indicator - wanna to switch of

Is there any possibility to switch of the blue lighting indicator on switch on? I usualy use odyssey as a NAS server (Debian) so i would like that the working board doesnt emiss any light ans sound ( also the blue light associates insects - so as i put it in my basements i would like to avoid that as much as possible )
Actually on my router I can switch all leds off, so is there any possibility, also, to switch of LAN (green and yellow) indiocators on odyssei?
