From the online help:
Use To Determine Row Suppression (columns only😞 Set to True to improve performance on large cube views by enabling the designer to better define how to apply row suppression.
So no, you don't have that option for rows. You could pivot your layout, or try some Conditional Formatting trickery (e.g. setting the font color the same as background color if there is data on the other row). Or use an override that points to a calculated UD8, returning nodata as necessary (which will trigger suppression).
