    Hi, you can't Windows security won't allow to rollback BIOS. The only way is to ask Acer Services in your country to reprogram the EEPROM, don't try to flash with a USB stick as that will brick your laptop,

    You need to reprogram the bios chip completely with an earlier bios version and that needs a special Adapter 24/25 Series USB Programmer Clip BIOS Writer CH341A*1 Tool and its proper software which you need to know how to use, as if you don't you will BRICK the bios chip.

    Why do you want to roll back the Nitro AN515-44 laptops bios? What is wrong with the bios 1.04 and what is it doing to your laptop? Tell us why as we can advise you what to do and what is wrong with your laptop, its very rare that you will need to roll back a bios to fix a problem as bios versions are released by Acer to fix issues like in version 1.04 of the AN515-44 it does this "1. Add for new panel ID".
