Your problem is about the evil mode(or anything hooks with it) not the org-roam itself…

This is link example with org-roam id:

something interesting is in this [[id:aaaa-aaa-aaa-aaaa-aaaa][A]] link. Check it out...

This is link example with file location:

This is link example: something interesting is in this [[file:parent/b.org][B]] link. Check it out...

And they gonna look like this.
