We have chosen the journal to use double blind review (Settings>Workflow>Review).
However, when choosing reviewers for a submission we anyway get an option to choose double, single or open.
Is it possible to deactivate this option, so that an editor not choosing single-blind or open by mistake?
The journal setting sets the default for the editor when creating a new review; unless the editor explicitly changes the control, the journal setting default will be used. Totally disabling other kinds of reviews would require a modification.
