For space vector modulation, the main difference between variants is the distribution of the two redundant zero vectors. I could imagine that what you are referring to is the modulation with only one zero vector. There are different names for this such as "discontinuous modulation", "flat-top modulation" or "deadband PWM" . Only two phases are switched wheres the third one remains constant so that switching actions and switching losses are reduced by one third. Top and bottom may refer to which zero vector is used. So to implement it you have to adjust the times for the zero vectors accordingly.

For more information, I can recommend the book "Control in Power Electronics: Selected Problems" by Kazmierkowski et al.
