Daterange question

I have order-lines with start-end like this:
start_date DATE NOT NULL, end_date DATE, drange daterange NOT NULL GENERATED
ALWAYS AS (daterange(start_date, end_date, '[)')) STORED
and have an index on using gist(drange)

I want to list all order-lines which does not have end-date set in the past,
but want to show lines with start-dates in future.

This seems to do what I want:
NOT (drange << daterange(CURRENT_DATE, NULL, '[)'))
But this doesn't use the index.

Any idea how to write a query so it uses the index on drange?

Thanks.
