[Request] Unlock y720-15IKB 4K OLED Display support (whitelist?)

[zal16]

i have a Lenovo Legion Y720-15IKB laptop. Originally her came with a FullHD IPS panel, but i tried to upgrade to a ATNA56WR08, an 4K OLED Display. In addition to the display, I also bought a 40-pin eDP cable (there are y720 laptops that come with a 4K display, so I bought an official cable for that), but when I connect the cable and the OLED display, the notebook does not turn on. I suspect it has something to do with the whitelist lock.

I put my bios in the attachment (it's insyde), dumped it with an SPI programmer.
