[REQUEST] Lenovo Yoga 730-13IKB (7LCNxxWW) BIOS Unlock

[Lenskha]

Hello,
I would like to have the BIOS unlocked on my device, a Lenovo Yoga 730-13ikb. I'm a complete newbie on Bios modding but I've been searching for a week and I'm ready to buy an SPI programmer if necessary, but I need the actual modified BIOS to flash first. Also, what does RSA signed BIOS mean ?

Here is the official link to download the BIOS and here is what my BIOS currently looks like :

Have a good evening !
