Is it possible to generate code with int value instead of pointer as parameters?

I have a task to generate code for a onnx model, the input and output data are very small, e.g. 1 single int value. the code should be as fast as possible, so I want to generate code for the operator. But the PrimFunc I got at the backend of TVM have pointers as parameters in the func signature.

So my question is, is it possible to generate function with int/float values as paramters?
