Hi @chandanmohanty,
For I2C guidance, you can look into the S32K1 Reference Software or the RTD package, they include some examples for the I2C drivers:

You can find some guides on how to install S32 Design Studio, along with these packages from this community post: S32DS - list of HOWTOs - NXP Community
Unfortunately, the support for external modules is out of this community's scope. I would recommend contacting the distributor or manufacturer for support on this device.
Best regards,
Julián
