How to disable Home LED on the Joy-Con?

[WhiteAls]

Here is a video demonstrating the problem https://yadi.sk/d/7bsRwDPR40yv7Q
My Joy-Cons are super original - back from 2018 (Mario Odyssey batch).
Other applications (for example BetterJoy) can turn this LED off just fine.
Am I doing something wrong?

Does it appear on:
Settings tab -> Devices options -> Select your joy con in the Detected controlers list -> Check the right part of the window
?

it does, check the video pls. i did uncheck "Enable Home LED" checkbox. i tried to reconnect my joy-cons, tried to restart DS4Windows and nothing helped

I removed both controllers from Windows then paired it again and now LED is off. Strange behaviour
