Is it possible to modify generated code before cross-compile?

I want to follow this example.

https://kr.mathworks.com/help/autosar/ug/configure_externalmode.html

I mean,

I want to integrate adaptive autosar application with adaptive autosar platform. Also I will make it run on Raspberry Pi.

So I'm trying to cross compile to target Raspberry Pi hardware following this document below.

https://kr.mathworks.com/help/autosar/ug/configure_externalmode.html

However, I need to modify the generated code to suitable my autosar platform (There is some Non standard function of official autosar platform)

And also There is comment in generated code like this

/* This file contains ARA Function Cluster ara::com stub implementation.
   This implementation can be used to compile the generated code
   in Simulink. When deploying the generated code outside of Simulink,
   replace this file with an appropriate ARA file.

   Code generated for Simulink Adaptive model: "test"
   AUTOSAR AP Release: "20-11"
   On: "XX-XX-2024 XX:XX:XX"  */

But I have to cross-compile by targeting the hardware using xcp.

When cross-compiling with xcp, is it possible to separate process between code generation and compilation?

Is it possible to cross-compile after modifying the generated code in this way?
