Location of BIOS chip (Thinkpad E14 Gen2)

I am working on my Lenovo Thnkpad e14 Gen 2, and was updating the BIOS. I lost power to the device during the update, and now I have a bricked device. I have tried all the simple fixes to no avail. I am looking to replace the BIOS chip, but I haven't been able to find a schematic with its location. The board is 5B20W77573. The device is out of warranty, and I am comfortable in soldering the replacement chip in place. Any assistance would be greatly appreciated.
