I don't know. I think I can do it. So now, we know that it's integrated to the main BIOS. I will download the BIOS from Acer, and if i can see it, i will try it. I will have to watch some BIOS update videos, because for laptops it's diffetent.
Yes, the CMD is running as admin. And there are no BIOS(e?)s uplodaded to TechPowerUp. Maybe I will try the Linux version of nvflash, and maybe that can read the BIOS. My laptop model: Acer Aspire E5-571G-69D4
