@ChuwiSpainSupport, Hello, I have a FreeBook, but really don’t like the auto backlight off either. My serial number is ZFreeBCY6H231100221. It is a chuwi freebook 2023 with i3-1215u and 12gb ram. Is there any way to also get a modified BIOS for my device? Thanks in advance. ---

For previous model, people posted CPU-Z showing RAM at 2400 (2394 if exactly) frequency with 52-44-44-108 timings, but mine got RAM at 2000 (1995 if exactly) frequency (effective 4000) with 48-36-36-84 timings.
