How to format a SD card to FAT32 and remove EFI partition

I have some SD cards with an EFI partition which I cannot use in my 3D printer. To get rid of the EFI partition you need to format the SD card with a MBRformat parameter. First use diskutil to find your disk position.

diskutil list

diskutil eraseDisk MS-DOS FAT32 MBRformat /dev/disk2

And afterwards if you check again with diskutil list

You will see that the EFI partition is gone.
