I’m sure if you had a big enough order you could buy them from a company with those specifications.
But if you just overwrite the disks anyway and assume they are blank it will be the same. For example.lets say you buy 10 SD cards that are fat32 formatted. If you need to write an image to them then just write over the entire disk with something like dd or a similar tool on windows. You only need to destroy the first few MB of space to nuke the MBR. Gpt is a bit more complex as it stores a backup table at the end of the drive. But it doesn’t really matter if you overwrite it.
