Can a modded BIOS solve the Invalid SN of Lenovo Legion Y740

That is unexpected, to pass #2 now when you had to disable some stuff to pass it before. Are you sure BIOS version was downgraded?
If yes, then maybe they already had those things disabled in older BIOS but enabled in new BIOS.

Thank you for your fast response. Yah I made a backflash to 1.05 and it’s successful. The step #2 on FPT was also successful. I attached some images here, including the BIOS version, FPT log and Vars.

On GSync, he'll have to explain that to me. Are you SURE you have RTX card? Show image of GPU-z with the RTX card selected at bottom drop out menu.

for G-sync I’m sure I’m on RTX (2060). I attached the GPU-Z image

I was thinking, since this may be a replacement board, your current in BIOS serial I mentioned above, may be correct one, and the one I showed image above on the sticker may be from the original system and just that part the sticker on is original but the board was replaced.
None of that should matter to anything other than you visually seeing a serial # in some apps, and or windows activation via in-BIOS key (which is missing, thus this does not matter)

Generally speaking, this stuff such as Serial, UUID etc are only used to activate windows, or for warranty purposes etc.
They do not affect system functionality, so none of this once fixed will help any functions if that is what you're goal here is, other than maybe some Lenovo specific program may not work correctly until we fix this.

At first I just hope to fix the info so that I could use all Vantage and Magic Y Key features. However after I heard the mention of G-sync from @dglt I thought I faced a severe problem. I looked up my panel (BOE083B) and many other users also confirmed the presence of G-sync.
The info is not for warranty or any kind of genuine contacting as I purchased it from a shop and they only offered one month warranty at shop. Now I even dont think I got enough genuine information on the device

I have a question. Does each parameter need to match each of the others?
