These are all the unlocked settings on an Acer Helios 300 laptop with InsydeH2O UEFI firmware. Providing instructions as to how to do this isn’t trivial, and involves using a hardware SPI programmer to dump the BIOS from the chip on the laptop’s motherboard, modifying it to unlock the settings, and then flashing it back over the hardware programmer; this requires its own video and explanation. This video is meant to show the settings, and isn’t a guide to perform the BIOS settings unlock.
I specifically used a Raspberry Pi with a Pomona 5250 SOIC8 clip to dump and reflash the BIOS chip with flashrom, and this has worked on 3 different Helios 300 laptops (Skylake, Kaby Lake, Coffee Lake). I mainly wanted to be able to disable Hyper-threading and legacy USB support.
