Hi, my phone is disabled and it is iPhone X. What should I do to keep my phone information on the device?

No, they cannot. All Apple could do is the same thing - restore the device, erasing it in the process to reset it. Erasing a disabled device by restoring it is the ONLY method to reset it. There are no alternatives.

It is too late to save your data. You need to restore your phone and then reload your most recent backup.

By deliberate design, there is no way to reset a disabled device without erasing it. Once disabled, there is no mechanism to reset the device and not lose data if you had not already made an iCloud or iTunes backup.
