i have a custom build pc and i need to update the bios on my asus motherboard but im new to this and not exactly sure how can someone please tell me

Así que compré una placa base ASUS nueva para cambiar la frecuencia de mi RAM, pero necesito actualizar la BIOS para usar la serie Ryzen 5000, mi problema es que no tengo una CPU inferior, así que no sé cómo puedo actualizar la BIOS si no puedo acceder a ella.

I wanted to share my poor experiences with my asus tuf laptop:

I have an asus tuf a15 fa506ihrb 2021, my laptop is generally forgotten my asus (i have to use different tuf a15 drivers because mine doesnt have drivers from asus themselves, so i decided to install windows 10 iot ltsc 2021 (updates till 2032) and i was a bit scared when it showed me a bios update via windows update, but i decided to go with it, then it was stuck on downloading the actual windows update, when i restarted. solution was to turn off router/remove ethernet so i can successfully update the bios then update windows itself, then it worked fine. i really need to disable asus auto bios updates so i dont get a heart attack next time. Any help is appreciated.

Edit: now i need to use DDU to remove the updated drivers, i had NimeZ amd drivers, im annoyed!

note: I use G-Helper and dont want to ruin its functionality, Thanks to the devs of G-Helper!

How to properly update bios?

Firstly I would like to state that I am not super tech savvy by any means. I will be receiving the Asus ROG Strix Z790-e by the 16th. I have gone and looked into a lot of resources in regards to this mb and I have noticed that on the asus website that it says when updating the bios to please download the Intel ME Update to ensure optimized system settings. Do I need to completely boot the system download Windows 11 just to update the Intel ME Update before just flashing the motherboard to the newest Bios Version 0816? How would you go about this? I know I am ignorant but wish to be enlightened. Thanks for any and all helpful responses. As it stands I was going to update the bios before even downloading Windows 11 but idk if it will cause instability since they want me to download the Intel ME first.

System Specs:

Asus Rog Strix Z790-e, Intel 13900k, 2x32 G-Skill 6400, 2x2TB Samsung 990 Pro and Asus 4090 Strix OC.
