No pgUp or pgDown keys to use telemetry options

First of all let me mention that my laptop does not have any page up or page down key
so usually what I could do is to press the Fn and then the down or up arrow. Well for some reason it’s not working

I wanted to check the telemetry options but I couldn’t I also tried to change the key settings on the keyboard but I can’t

So is there any idea what i can do here?
