Uhm.. no: to act ethically you (reasonably) need to study ethics.
Do not confuse ethics and morality.
Studing ethics is not enouth to be ethical, sure, but it is required.
Being good is different from being ethical, for example. Adherence to a certain form of morality is not being ethical. But ethics is a deep branch of phylosophy and for sure I'm not qualified to teach it (over mastodon :-D)
Anyway, good night!
