Hi,
there are only general SPI examples:
If you use SDK in S32DS:
c:\NXP\S32DS_ARM_v2.2\S32DS\software\S32SDK_S32K1xx_RTM_3.0.0\examples\S32K148\driver_examples\communication\lpspi_dma\
c:\NXP\S32DS_ARM_v2.2\S32DS\software\S32SDK_S32K1xx_RTM_3.0.0\examples\S32K148\driver_examples\communication\lpspi_transfer\
c:\NXP\S32DS_ARM_v2.2\S32DS\software\S32SDK_S32K1xx_RTM_3.0.0\examples\S32K148\driver_examples\communication\spi_pal\
If you don't use SDK:

Unfortunately I'm not aware of example for such displays.
