It is mentioned that in Asia Pacific and Europe, self-study options
are not available and only the instructor-led training with courseware

I didn't found this info on their website. So asked info () eccouncil org
They didn't answer me. I have more than 3 years experience in IT field
(Security).

Am I able to take exam without taking a course?
