How to access advanced BIOS (UEFI)

Before I start writing anything, if you have answers, please make them really clear. For example; at what point do I need to hold or release the FN key? I have tried many methods such as;

-FN+R+N followed by F10 and Enter.

-Shut down the computer, press FN+r+n, open the computer and press F2.

-FN + all keys from Q to P, A to L, Z to M.

-To look for the manual of my motherboard, there is no place explaining/helping as far as I've seen..

Here are the information that may be necessary;

Laptop full name and model: Slim 7 Pro-14IHU5 Laptop (IdeaPad) - Type 82QT

Bios version: FJCN75WW

I can provide any additional information if needed. Thanks in advance..

The easiest way to enter the BIOS on your machine according to the manual here: https://download.lenovo.com/consumer/mobiles_pub/yoga_slim_7_pro_ug_en.pdf is to press the hidden NOVO button when the machine is off - see pages 7 and 15. Or press Fn + Power button from off.

Otherwise press F2 (or Fn+F2) rapidly and repeatedly just after powering-on.

Im not looking to enter regular BIOS, there is a place you can enter only when you enter a specific key combination. Here is a video what Im talking about;

The other way is to use MS Defaults to get the Screen for Trouble shooting MS or to enter UEFI from it as well as DOS, Troubleshoot   https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/boot-to-uefi-mode-or-legacy-bios-mode?view=windows-11  more or less same for 10

As I see the Video you posted, once in the "normal" BIOS the sequence seems to be:

Fn+R, Fn+N, F10, Enter, then repeatedly hit F2 as the machine re-boots.

It may be that this sequence only applies to certain versions of the BIOS - is yours up to date?
