How do I change the metadata, xmp (for change data creation file)of an AI file (Illustrator) Help

[Matteo5C1E]

I need to change the creation and modification date of an Illustrator file, I've tried with some applications but when I enter Illustrator >>>>>File Info, the change doesn't happen.
It is really urgent and I would like to know how I can do it.

Hi, if you are using Mac you can use TERMINAL, there are many tutorials in youtube and I think PC will be similar
