Can you disable Find My Mac (and iCloud) without the iCloud password on a Mac?If all you had was a login password, that is easy to reset, then login and turn off iCloud and Find my Mac. So yes, if you turn off iCloud, it is also turned off in NVRAM like I mentioned. But if you have Filevault encryption turned on, the thief would have no way to get in and turn off iCloud, so FMM would stay active in NVRAM even if you reformatted or removed the drive.
