Second NVME for white list enabled Lenovo Thinkpad x13s. This laptop have white list only in second (wwan) m2 port.

Main idea, we modify NVME pci id's to look like a white-list allowed device (i.e. modem/wifi/etc)

First we should find white-listed VID/PID/SSVID/SSPID, for thinkpad x13s i just read a bios firmware and found this part of data, well it looks like id's and repeated like a list of them

0000000001000000 5B10 C1E0 CB17 0C01
0000000001000000 5B10 C2E0 CB17 0C01
0000000001000000 5B10 C3E0 CB17 0C01

0000000001000000 105B E0C2 17CB 010C
0000000001000000 105B E0C3 17CB 010C

yes! i googled this and verify what that's it. 105B/E0C1/17CB/010C VID/PID/SUBVID/SUBPID

Then we should find capatible nvme drive for flashing, thinkpad x13s have two m.2 2242 ports: first one without white-list have 4 pci line is used for main nvme, second one with white-list is key_B port for 5g modem with 2 pcie line,

I found NETAC N930ES 2242 drive with both of keys(M+B) and compatible for flashing sm2263XT controller + YMTC memory cips. using a SMI MPTool i changed drive id's to correct one and succefully pass white-list and boot the system, Windows and Linux OS recognise drive correctly, also it shows in bios screen in same way like main nvme.

here is a details, SSD-X13s-256G - is out patient:
