Chuwi herobox opciones avanzadas en Bios

Hola he adquirido un mini pc chuwi herobox pero tengo algunos problemas y creo que es por la configuracion de fabrica. He entrado en la Bios para modificar los ajustes de cpu pero no tengo la pestaña “avanzado” que si que he visto en videos que esta por lo que no puedo modificar la velocidad de cpu y creo que ahi est el problema . Alguna solucion??

I’m also interested on this. I’ve seen videos in which BIOS is unlocked:

To access the “Advanced” tab in BIOS, here’s the method I used(but keep in mid its a strange one, at least I didnt know about this, I stumble on it by accident): just add a SSD on SSD bay(SATA connection).

I added a SSD to expand the storage and even to install a secondary OS, then I’ve entered the BIOS to set it up as primary, and there you go surprise - the Advanced tab was unlocked.

It seems the activation of “Advance” tab in BIOS is not a constant thing, one day is on and the next day is off by itself, which is bizarre, but the good thing is that it does appear again.
