Can I apply for a Greek visa directly in Turkey?

No, you can't apply for a Greek visa directly in Turkey.

Mainly because Greece is a Schengen country, it needs to be handled according to the requirements of the Schengen visa.

Only when the following conditions are met, can it be handled directly in Turkey:

Applicants must be born, live or work in the country before they can apply locally, and must submit the original documents for inspection.

Applicants must stay in foreign countries for more than 6 months before they can apply for visas from other countries in their host countries.

Just to remind you, the relationship between Turkey and Greece is not very good ... so it is not recommended to handle it in Turkey. It is best to handle it in advance to prevent the inconvenience caused by accidents such as rejection.
