Thank you for contacting us with this question.
For now there is no such option to modify object permissions for Profiles, and we will add this to our backlog for the next releases, as we'll work on the Admin/Declarative functionality.
If you dont mind me asking you - how you'd prefer to configure this settings? From an admin panel or from the sObject editor (from the "object perspective") or you'd prefer it to be from the "profile perspective" so you'll see and configure all objects for a chosen profile? This will help us bringing the better experience for you :)
