Lenovo Ideapad D330-10IGM eeprom?

Hey folks,
I got the mentioned tablet pc from ebay for cheap and repaired it.
Unfortunately there's a bios password set so I can't disable secure boot which is a problem for me. I'm an electrician and familiar with electronic circuits and smd soldering. I've reballed gpus and vrams many times. Now what should I do? Get a new eeprom with bios included? (haven't found any). Or can I somehow bypass the password check once so I can atleast get into bios and turn off secure boot and i'm good? Also I don't know how to find the bios eeprom...
