It's different with all mobos but normally by turning off Secure Boot and enabling Legacy BIOS the choices for EFI in BIOS Boot Priority list disappear. If not look for another HDD choice in that list or the storage options.
If this remains a sticking point then you'll need to query your mobo manufacturer about this, perhaps in their forum. The manual is also on their Support Downloads webpage. Google may yield more about it including specifics for your problem. It may also only yield this thread which means we are pioneering the issue.
