Emacs never hides CRLF EOLs unless it says "DOS" in the mode line.  If
your file has mixed EOL format, then either you will see "DOS" in the
mode line or some of the lines will have ^M characters at their end.

If you see neither of these, then it isn't Emacs that converts some
lines to DOS CRLF format, it's some other program.  And you didn't
describe in enough detail what you do to try guessing more.
