Depending on what model and make of drive you have, you may be able to get unsupported firmware from the likes of rpc1.org. Using such firmware will void your warranty, because manufacturers are not allowed to support that capability in drives sold to the general public. Original Apple firmware is very hard to obtain for most drives, so this should be considered a permanent change.
It's easy to destroy a drive by flashing it with incorrect firmware, so make sure to research this thoroughly before proceeding.
