Hacking Backup Loader with Ocarina Removed/Disabled?

[PopSmith]

My little brother is beating games I've been downloading for him way too quickly because he is just cheating his way through the games.

Is it possible to remove Ocarina from Configurable USB Loader? If not, is there another USB Loader I could use instead that has Ocarina removed or that allows me to remove Ocarina semi-permanently (i.e. aside from an update)?

EDIT: My games are on a FAT32-formatted HDD.
