How does Adobe Acrobat / Reader identifies URLs ?

Adobe Acrobat / Reader identifies URLs in the pdf file, how does it identifies.

I have a requirement from my organization to change the link suggestion text to normal text in pdf files, how can I achieve this using script. We have option create links from URLs in general preference, if we disable this option I will get what I am expecting, but this is manual process. I want the same process through automation (Script).
