How can we hide Source Tracking from the application process?

Summary

Streamlining the application process

Hello!

 

We're currently reviewing our application process to reduce the number of questions, for a period of time we would like to remove this section. I can find it under application flows but not sure how to remove? I assumed may need to deactivate to be able to edit but get the error message below, any suggestions appreciated,

Thanks

Kevin
