Airtime Fairness. How do I check if its enabled? Slate AX

[Denisimo]

Im still learning OpenWrt and the commands via SSH. How do I check if Slate AX has airtime fairness enabled and how do I turn it On if its disabled?

Cheers.

edit;

I tried this command and im getting a list of denied permissions.

grep -rl "airtime" /sys

Airtime Fairness is already enabled in the default, and not recommended to close.

Why do you need it disable?

[Denisimo]

I don't want to disable it, I just want to check if its enabled in the first place.

Cheers.
