The best way to manage automatic citation behavior in EBSCO is to sign into your EBSCO account and edit your preferences.

Once you're viewing search results in EBSCO, you can click the button "EBSCO sign in" and either log in with Google/your EBSCO account or create an account manually (link below the entry fields).

Once you're signed in, click on Preferences in the header menu and edit your preferences for citation style to whatever you would like. Here's a link to EBSCO's help on this topic: https://connect.ebsco.com/s/article/Setting-Preferences-in-EBSCO-Interfaces?language=en_US

There is also a cite feature that can be used throughout EBSCO: https://connect.ebsco.com/s/article/How-to-Use-the-EBSCO-Cite-feature?language=en_US
