Clear bios password Acer Veriton EN76G (VEN76G)

Good morning everyone. I need to clear the bios password of my acer VEN76G:
I tried the three wrong password method but it doesn’t give me any unlock code, in fact it’s no longer possible to enter passwords and I have to turn off the PC. I honestly don’t know what type of Acer bios it is, I only know that it is different from what I see in the various video tutorials.
