3-Phase Inverter Control with SPWM(Sinusoidal PWM) for 3-phase sinusoidal output
Yes you can and this is a common tactic.
It significantly reduces switching losses as for 1/3 of the time a leg will not be switching.

It comes with a couple a considerations.


Increase ripple current for the same switching frequency
The starpoint of the load will have a large common mode swing. 


If these two points can be tolerated, this discontinuous PWM scheme is viable
