I bought hp_elite_x2_1012_g1 secondhand. I accidentally found out that the BIOS was blocked in it. I took it apart and found a Winbond 25q128fvpq flash drive, in an 8wson case similar to a BGA. I soldered the wires directly to the legs of the chip. I read the vvdi-prog dump. Clicked open with RCUnlocker.exe. the resulting file was written to the chip. laptop is unlocked. Thank you very much to the creator of this wonderful program!
I am attaching the dump, maybe it will be useful to someone​...
