Lenovo IdeaPad Gaming 3 15IMH05 - 81Y40043MH

I just want to play Valorant... Have spent the last 40 minutes looking up ways to turn on secure boot but it's absolutely not working. Any tips?

Edit: added this pic because BIOS is giving me anxiety

Lenovo has been notorious of not allowing users to access advance bios settings, but recently I have found a way to access this options in the bios menu. I have only tested this on Lenovo Ideapad gaming 3 15ACH6. Steps are as follow:Step 1: Turn off you laptop completelyStep 2 : Press the power button to turn onStep 3 : Spam F2 to enter BIOS menuStep 4 : After entering BIOS, DO NOT PRESS ANYTHING EXCEPT THE FOLLOWING KEYS : Press Fn+R+N for 3 times.Step 5 : Press F10, then enter to save and exitStep 6 : Spam F2 again until you are in BIOSStep 7 : You should now see some hidden options, Enjoy!

WARNING: By doing this, you *may* void your warranty or damage your hardware. Make sure you know what you are doing before changing anything within the BIOS. I soft bricked my laptop twice when messing with the options. I am not responsible for any damage cause by accessing the advance optionsPersonally I only changes the cpu power profile to the 54W profile, along with the use of AATU(aka UXTU) I managed to increase the performance by quite a bit. CinebenchR23 score before tweaking was 8906, but after tweaking the score increased to 11233 while maintaining <95℃. There are options for RAM speed but I didnt use those because I am not familiar with them. I really dont understand why Lenovo have to limit this laptop so much and not give us any easy option to boost the performance, there are plenty of thermal headroom in this machine. And total power isnt a problem as the cpu can run at 50W with gpu at 90W for over 10 minutes without any problem(no throttling no thermal problem). Lenovo why?Credit : I saw this method from https://youtu.be/mmd4Sc5bVcIAATU/UXTU : https://github.com/JamesCJ60/Universal-x86-Tuning-Utility

No bootable usb and no SSD showing up in yhr booting menu. Only this EFI PXE thing. SSD is recognized in the BIOS info. The usb does light up when connected and the laptop is brand new. Any suggestions on how to install Windows ?

Bios: EGCN36WW
(Had seen an newer version, 40ww on support.lenovo.com, but Vantage doesn't seem to recommend it when searching for updates)

I had read somewhere on the net that there are power saving options that maybe available in the advanced bios. Planning to take a look at the options and try them if they are safe.

I have tried the Fn + R+ N (x3) option after pressing F2(ending up in the screen with the option to change the boot order of drives). Have also tried it after clicking on more settings there and entering the bios settings.

Thanks in advance.
