is possible to chip a 2014 GS300H ?

As it's an naturally aspired engine gains would be very low, combined with the atkinson cycle of the engine it is not the best candidate for chiptuning. Sorry to tell you but it is what it is. An eco base engine that is reliable and well running, want more horses get a 450h you will be impressed :-)

Yup, grab a bunch of pebbles and throw it at the car. You'll have many chips.
