[U-Boot] Disable command at runtime

Hello,

I wonder whether it is possible to dynamically enable/disable a command. Since u-boot does not provide any secure authentication method, it is dangerous to keep some commands available to a potential hacker. E.g. the "fuse" command. On the other hand, I need these commands during the manufacturing process. So my idea is to enable/disable the commands dynamically based on some obscure logic. Is there a way to do it without need to deeply hack the code?

Thanks,

Petr
