TPPSDK(GD3000 Driver)

Hi , Experts, we want design a BLDC controller using S32K3XX and GD3000 which can control two BLDCs, so it need two GD3000, From the TPPSDK of GD3000's example, I found that the CS of SPI communication of S32K344 is controlled by SIUL2.

Now if I want to use a S32K344 to communicate with two GD3000s in a chain:

should I change the source code of TPPSDK to make the CS conrolled by LPSPI?

by the way , I want to ask you guys why the chipselect of spi communication is designed to controlled by SIUL2/Port/Dio......? Isn't it better if it directly controlled by LPSPI itself?
