How do I find the serial number of the video card?

Is it possible to find out the serial number of a video card using programs on the PC itself, for example, using everest? If you can't find it like that, then where is it located on the video card itself (Gigabyte GTX 970 G1 Gaming) or in the Bios? There is no box, I threw it away. I need a serial number to participate in Nvidia's Rise Of The Tomb Raider promotion
