Hello,
You could use the ini values in a way, that they must present some secret string, if not present or not as expected, then the options will work "default".
An easy way to do so might be the hash code of the EXE file, that will change every time you rollout a new version. Have a look at
C:\Program Files (x86)\AutoIt3\Examples\Helpfile\_Crypt_HashFile.au3
