Good question. I just had a squint at the SAM3X datasheet. I didn't see anything that looked like a fuse. They have some "lock regions" in flash, and a "security bit" which can be set to prevent any external access to flash (so nobody can download and hack your executable).
So far, I haven't seen anything that can't be undone. Unsetting the security bit simply requires wiping the flash.
It looks like no bricking is possible, so go ahead - do yer worst! :wink:
