Control keyboard backlight via command line on IdeaPad 5 slim 16IRL8

I use arch linux and the reason I want this so bad is because my computer doesn't remember the backlight state and turns it on every boot and every time it wakes from deep sleep and I mostly don't need it. Referring to archwiki I tried both brightnessctl and xset but none of them seemed to detect it. my /sys/class/leds/ looks like

input3::capslock
input3::numlock
input3::scrolllock
phy0-led

there is neither a ::kbd_backlight nor a ::thinklight directory most solutions online are based on them
