buyers may be gamers who aren't into mining...
What do you think is the best to do?
It depends on the buyer to whom you sell your graphics cards.
If the buyer takes 1 video card, then I install the original BIOS for him. I try to keep all the original BIOSes of the video cards. If you sell video cards in batches of 5-10 pcs, then your buyer is a miner who needs an original BIOS.
It is important to install the original BIOS when you contact the warranty service
