Hi Saad,
I'm checking this with the latest SDK version (v2.9.2).

You can configure this macro by the property named "Enable time slicing".
"yes" generates #define configUSE_TIME_SLICING 1
"no" generates #define configUSE_TIME_SLICING 0

Note:
if you have some older EAR version of SDK I'd suggest you to update your S32DS to the latest greatest version (https://community.nxp.com/docs/DOC-342194 )
Hope it helps.
Stan
