[Request] Unlock BIOS for Miix 3-1030 Tablet (Lenovo)

[Tom027]

Hi, I'm new here, so please forgive me my current state of knowledge in this topic. 

I would love to reach advanced tab in the BIOS settings in order to install some Linux distros. 

Unfortunately, I gave up after two days of searching the web trying to find the correct tutorial. 

Please, can someone help me with the process of unlocking this BIOS?
