Permanently Unlock iCloud Activation Lock on iPhone 11

I am seeking professional assistance to permanently unlock the iCloud Activation Lock on my iPhone 11, which is running iOS 18.2.0 and powered by the A12 Bionic chip. The device is currently activation-locked, and I am unable to access its full functionality. This project involves bypassing or removing the iCloud lock while ensuring that the device remains functional and fully accessible afterward.

Requirements:
iCloud Lock Removal:

The unlocking must be permanent and allow me to link my own Apple ID to the device.
No temporary bypass solutions unless they lead to a permanent unlock.
Compliance and Security:

The process should be safe, legal, and comply with Apple’s security protocols wherever possible.
Any tools, software, or methods used must not compromise the integrity of the device.
Experience and Expertise:

Proven expertise in iCloud Activation Lock removal on iOS devices, particularly for iPhones with A12 Bionic chips running the latest iOS versions.
Familiarity with iOS 18.2.0-specific challenges and tools.
Data Protection:

Ensure that all data currently on the device remains intact, or clarify beforehand if data loss is unavoidable.
Additional Information:
I can provide proof of ownership (if required).
The Apple ID credentials for the original account linked to the device are not available.
Deliverables:
A fully unlocked iPhone 11 with the iCloud Activation Lock permanently removed.
The ability to sign in with my Apple ID without any restrictions.
Documentation of the process used (if applicable) for transparency.
Assurance of no recurring issues or re-locking after updates.
Timeline:
The project should be completed as soon as possible, preferably within 3–5 business days.
