iMX6_SOLOX_3V3

My questions are concerning of powering the microprocessor   iMX6 SOLOX from a 3.3 volts input power source. For power sequencing I use the preprogrammed PMIC chip MMPF0200F6AEP. But I would like not to use the SW2 output of the PMIC as a source of 3.3 volts for my PCB. I plan to use the input voltage and a load switch instead of use the SW2 output of the PMIC. To control of the load switch I want to use the output voltage of the SW3A output of the PMIC. Is it correct using of PMIC? If so, may I leave unconnected the pins SW2LX, SW2IN, SW2FB of the PMIC chip MMPF0200F6AEP? Or I must connect them as in the MCIMX6SX SDB board  (SCH-27962)? Is it mandatory to have 3.3 volts on the SW2 output for correct operation the chip MMPF0200F6AEP?
