I'm looking for solution with 0.4Vout to 3Vout/2A adjustable output from 3.1Vin. Does TPS546A24A support 3.1Vin to 3Vout?

No, the TPS546A24A will not support 3.1V to 3.0V due to the minimum off-time requirements imposed by the low-side MOSFET current sense.
I don't believe any of our PMBus parts will support the >97% duty-cycle required to support 3.0V output from 3.1V input. You will likely need to look for an external adjustable output voltage solution, such as using an externally programmable reference voltage or feeding a current from an external DAC into the FB pin of an analog converter.
