Hi Rasa,
Not a problem. Differences would be in connecting over the four SPI wires in the BOOSTXL-DRV8323RS to the Raspberry Pi instead of the single MODE pin. The other connections I outlined above are the same.
Also, I forgot to add in my initial steps, be sure to connect the GROUND of the BOOSTXL-DRV8323RS and the GROUND of the Raspberry Pi together, otherwise you will not be able to communicate between the two PCBs.
