Unlocking CFG Lock in Acer BIOS

[david20040]

Sup folks! I've got a new laptop (ACER ASPIRE E5-573G-55MH) and decided to install macOS on it. However, I need to disable CFG Lock in BIOS but I can't find it anywhere (I've tried to look in advanced tab too). I don't know how to dump bios, it's giving me an error. 

 BIOS: https://global-download.acer.com/GDFiles...SC=EMEA_22

 LAPTOP: https://www.acer.com/ro-ro/support?searc...l_download

Can anyone help me out? I will appreciate if so. Thhanks!

PS: I can't open the bios executable file on Windows. It seems to be loading but immediately closes.

Go advanced bios,
1. Turn off laptop first
2. When laptop is turn off, hold fn+tab and before acer logo come you must release fn+tab and click f2 many times
3. find cfg lock in advanced>cpu>cfg lock>disable
