I've been doing several tutorials for several days to try to modify my BIOS (ASUS TUF Gaming B550M-Plus) but without success.
I wanted to show the functions that are hidden in the bios, at first I was interested in disabling HPET and LTR. both are hidden in the BIOS and via SCEWIN as well.
Can anyone help me with this mod? I would really appreciate it!

I did a
test mod ,try this then respond to the result.
I really appreciate it for you are helping me, I was able to install the bios, the computer started normal. But I can't make changes to the bios because it crashes.
And when I spend a long time just looking at the bios it also crashes.
I have no idea what it could be.

1. What does crashed mean? freeze or something when you move mouse or scroll??
2. For a long time ago, i've unlocked another ASUS
B550 mainboard ,i applies the same edit way to yours ,so it should work , i don't know why it crashed.
3. Have you noticed a thing ,when you open the official bios via AMIBCP ,it will not present the setup menus normally ,this is because that the recently release bios isn't a complete bios image. Or should say ASUS separate some modules. The same situation in Intel machines ,such as 10th gan laptops ,g732lws ,g512lv..etc. So , we only can manusally edit setup module and amitse to unlock hidden sections. Therefoce ,it maybe the reasons to caused crashed i guess.
Now i don't realize how to combine or extract the bios image correctly ,Asus is so sneaky.
The bios freezes and the mouse freezes too and a few seconds later the computer restarts.
Should I install the bios again?

1. Now you should to do is revert bios via official bios. The original designed feature of flash button is in order to recover bios ,so you don't need to worry it brick.
2. These are another
test mods ,if they are still get crash ,i have no ideas. Because I don't know why it crashed.
I just tested all the bios, tested with three different pen drivers and also tested formatting them in different ways.
The last two MODS do not open the BIOS, I press delete to enter the bios and there is a black screen and it does not enter and after a long time the computer restarts. the last two MODS this happens.
(I reverted to official bios and then tested one, reverted to official and tested the other. I don't know if it was necessary but I did it like this.)
Regarding the first, it was the one that came closest to working. I liked it a lot, I can browse the bios and see all the options that weren't there before and are now appearing. but I can't make any changes that the screen freezes and then the computer restarts.
I don't really have no idea why this happens, sorry for the question, but it could be related to the amount of options and the bios chip didn't support it because of space?
too sad I don't know what else to test, I really appreciate it for helping me.

1. Usb stick format to fat32 is better.
2. The result was not i expected ,no.2 & no.3 only do a easy test for tab unlock ,so it should not get black screen. Could you see new Chipset in no.1 mod?
3.
4+5
Yes I can see the new CHIPSET tab on 1 and 5.
MODS 4 and 5 worked perfectly, I was able to make changes and save to both.
In 4 apparently all options are hidden. 5 has the new CHIPSET tab you mentioned, but all the other options are hidden as well.
Could it be that taking away languages and other irrelevant things wouldn't this 1 work? there seems to be very little left.
