[Request] Sony SVD13215PLB Bios Unlock

Hi, I bought a Vaio Duo 13 recently but the advanced menu cannot be accessed in the bios options. So I'm not able to install any linux distribution on this ultrabook. Turning the secure boot option OFF doesn't help. And I need to enable the legacy mode on the boot menu which is not available.

Model: SVD13215PLB

These are the Bios files:

Executable: Link

Extracted ROM file: Link

I hope someone could help me out please

Thanks
