I am not from Intel so I could easily be wrong, but perhaps it is updated by the provider of your BIOS. For example in the release notes for latest BIOS update of Intel NUC DN2820FYKH it says Updated graphics GOP Driver to version 7.2.1011
i known it...but i can not update the bios of my table pc .i want to update gop driver by myself.
You would not be able to update a GOP driver directly since it is part of the firmware. But generally it is not necessary to update in this manner, please let me know what is your system brand and model and why would you need to update the GOP driver specifically.
