Disabling Leds?

I m building MT on solar system I want to save power as much as possible
Is it possible to disable leds
system leds> is empty so I cant do disable

/system leds> print
Flags: X - disabled, * - default

TYPE INTERFACE LEDS

/system leds> disable numbers=1
no such item
/system leds>

ps. I search forum I find some old posts with similar topics but no answer/solution.

The answer is simple
yes or no
anyone from mt support?

I think they are off by default… but you can manually turn them off by doing:
:led user-led=no
:led led1=no
:led led2=no
etc.I do not know of any way to turn off the power LED.
