1 column only configuration for HA possible?

Is it possible to configure HA to have only 1 column? So cards will expand to be quite wide (e.g. history_graph)

If no, next best way to achieve a full width view of a component?

[ Note: I do also have a separate but somewhat related question re full size graph here: Full width history_graph? / how to set HA to be one column only? ]
