Help with Intel Low-Power encoder

[WheelFire]

Hello,

I'm a bit new to all this and also not a native speaker so forgive me for any dumb mistakes 😅

I'm running the latest version of Jellyfin on an Unraid server with an Intel Core i3-10105 cpu (iGPU is UHD 630).
I got hardware transcoding to work perfectly but I saw the Low-Power encoding options in the Jellyfin settings and figured it would relieve my cpu usage a bit.
I've read the docs and some other things on the internet about it but I can't find out if it's safe to enable this feature.

In the docs it says that to verify if the i915 HuC firmware is configured correctly you should run some commands (look here to see which ones). I've tried all three of them but they don't work because Unraid doesnt recognize the command (I've read that Unraid is running a different kind of linux called 'Slackware') 

Could anyone help me with checking if the firmware is configured correctly or how to configure it?

Thanks in advance!
