We don't have example for 2 layer design. But 2 layer PCB design is difficult to pass CISPER 25 as I know.

One suggestion is you can put VIN trace on top, and make the bottom layer for GND. and make SW as short as possilbe with shield inductor. and it is better to have differential and common choke to imporve the high frequency. the input fitler you can refer LMR33630-Q1 EVM User Guild

Thanks
