@Danissimode, Thanks for posting in Q&A. For the different displays of Endpoint detection and response, I guess the display of "Deploy an Endpoint detection and response policy to begin onboarding devices" is mainly with general setting to let new toucher to easy configure the setting.

Meanwhile, for the two different forums, Microsoft Q&A tends to be more of "Ask a question, get an answer" format where as the Microsoft Tech Community is a space to discuss with your peers, Microsoftees, MVPs and MCTs.
Hope the above information can help.
