To complete the previous answers, especially the one from @Devil, there is a bug for the Try It Out button on the springdoc-openapi 2.6.0. It is always visible, whatever values you set in the properties springdoc.swagger-ui.supportedSubmitMethods and springdoc.swagger-ui.try-it-out-enabled. The previous version 2.5.0 works fine, and the bug is supposed to be fixed for the future version 2.7.0.
