No existing Fn Lock command?

HP Recommended
HP Pavilion Laptop 15-cs1xxx
Microsoft Windows 10 (64-bit)

I've been searching for about an hour now for a way to lock my function keys in the F1-F12 mode or some way to reverse it so that the Fn key is used for the multimedia keys and have had no luck. My keyboard was not made with an Fn Lock symbol and I can't seem to get into the BIOs like everyone always talks about in other forums and how-tos. I got my laptop in October of last year, and it is a Pavilion Laptop 15-cs1xxx. Is there any way at all that I can enable function lock? 

I really don't see why it has to be different on different models. If there is no way to enable function lock with a keyboard short cut, why not make it something changeable in the settings? Is it that hard?

@KoKoPuffs Due to the current global COVID-19 situation, we're seeing an influx of customers coming in for support and we appreciate your patience.

That said, I hope you know that not all keyboards have an option to use the timeout feature by design, that's only available on limited devices, that said, here's all you need to know about using the backlight of your keyboard:


Toggle backlight settings:

If your notebook computer has a backlit keyboard, press the F5 or F4 (some models) key on the keyboard to turn the light on or off. It might be necessary to press the fn (function) key at the same time.

If the backlight icon  is not on the F5 key, look for the backlit keyboard key on the row of function keys.
