I added "Invalidate Data" settings to a datastream like this:
but instead of the widgets showing "--" after 10 seconds of no data, it seems to take around 12 to 14 hours before the existing values are replaced with "--" when no data is being sent to the datastream.
Edited to add - the data is being sent via an API call. Datastreams where data is being sent via Blynk.virtialWrites appear to work correctloy.
