Look for sdk_config.h it usually defined in there. It's an extremely big file with thousands of useless defines. Do a search in it. There is one for each project.

Alternatively you can follow this blog for an easy way to write firmware for the nRF. http://embeddedsoftdev.blogspot.com/2018/02/

Thank you. Do you know which of the files need to be modified in order to configure the pinout as well as the crystal and DC/DC? There are just so many things in the SDK that I'm having a hard time determining what is critical to the project and what is unused.

They work the same there is no required board definitions. The different with bare module is that no I/O are being use so you can use any. Some pins map are defined in boards folder of the sdk. You can define the pins you are using based on that. One thing to be aware of is whether the module has the 32768 Hz crystal and the DC/DC builtin are not. All SDK examples use them. If you module does not have it, you'll need to change the code to use internal RC and not activating the DC or you can add them on your PCB.

Ok, then I'll have to use the uVision application instead to program it. My main question still stands.

A jtag is require to program it. You can use JLink or IDAP-Link to flash it. SES only work with genuine Segger JLink only. From their website, there is no JLink mini.
