How to unlock advanced tab in BIOS?

Question

BIOS

Greetings!
Please help - you need to unlock advanced bios settings InsydeH20 r5.0 on ACER aspire es1-731g laptop.
Googled several ways:
1) Press fn + tab three times
2) fn + f2 + d
3) f2 + a

None of them helped me.

Maybe you need to reflash? I did not find firmware for this laptop on bios-mods.com, maybe it will come from some similar model?

Try setting a bios password and re-entering the settings with a password. Somehow faced with limited rights to settings in the absence of a password
