How do I unlink a device or third party? It’s a person close to me

Activation Lock is an anti-theft feature that cannot be bypassed. Only the previous owner can remove the lock. If the previous owner cannot or will not remove the lock, then the device is useless to you or anyone else. Apple will not help you find the previous owner. Try to get a refund or dispose of the device properly.

You're right,you are no expert because there isn't a way.

What Javaliga stated is completely true, if it wasn't you wouldn't be having this issue.
