A parameter for a module with modulename is defined in the file modulename_params.c. For instance mc_att_control has params defined in https://github.com/PX4/Firmware/blob/master/src/modules/mc_att_control/mc_att_control_params.c.

Then you can search for an existing parameter in the files and see how it’s done and then copy that. Let me know if that works for you.

Hey, we are building our custom firmware and want to hard code the parameter values so GCS cannot change it. Which files should we modify?

I think the best option is to create a custom airframe inside the init.d/airframe folder Adding a Frame Configuration | PX4 User Guide (v1.14)
Good practice is to start from a model that is already similar to your configuration
Than just add the parameters you want to hardcode by using param set-default
If you open an already existing airframe you will see it
