Sorry, I misread your post. “Destroy the restore partition”...no, that would be bad. ish.
You can probably wipe the main partition and restore from the restore partition BUT none of the data you wiped would be irretrievable. Then again, I believe they’ve had some luck restoring data from low-level-formatted, shot with a shotgun drives. If you’re truly paranoid about the data, you’ve got to pull the drive. If you just want it mostly inaccessible for all practical purposes, go ahead and wipe-and-restore.
