Hi, I’m having a problem, there is any way to change the iMac serial number? iMac14,4 Best regards, Nuno Martins

Sounds like the computer is iCloud locked. You will need to get the company to release it. Contact their IT person, as they may consider it their property.

It is possible, is a micro-soldering job and programming job (on new ones), and to be honest is cheaper changing the complete motherboard, unless you are planning to do it yourself.
