Unlocked BIOS dump for the Lenovo ThinkPad E495, marked as the first variant (1ST) and reported as tested OK, packed in a 4.25 MB RAR archive. Unlocked images of this kind are generally used to clear a supervisor password lock by writing them to the SPI flash with an external programmer. Before writing, read the original chip and keep the backup, and make sure the image size matches the flash capacity. Results depend on the exact board, so confirm your machine matches the variant indicated.
