Firmware archive for the HP Elite Dragonfly, with the name carrying what looks like an HP serial number, meaning the dump was read from one specific unit. At 18.8 MB compressed, it probably holds the full SPI image. A unit-specific dump contains that machine's identity data, so on another laptop the serial and settings may need editing. Use a programmer to write it, confirm the board matches, and preserve the original chip read before making any change.
