SharePoint Document location set only 1

Hi Folks,

I Set up Dynamics 365 (online) to use SharePoint Online

And Enable SharePoint document management for specific entities

Is it possible that i can disable this option set ? because what i am trying to achieve in this, is i want to have only one document default site since i only have 1 sharepoint. I am not sure why there is 3 Default site 1 in here.
