How to change Opencart Modifier?

Question

opencart

Good afternoon!
Tell me, please, how can I change a ready-made modifier in Opencart. Those. there is a template with built-in modifiers. Modifiers change controller/header.php if I want to add my data output to the header (address, fax, etc.) How and where can I find this modifier to add my variables to it?

Answer 1

enter immediately in the template, do not do stupid things
