I have confirmed that we don't have any option that turns off some of these variables but not others. As one of the other users posted, you can choose to go "All User Written" in which case we won't generate any code, it is entirely up to the user to generate whatever code they want. You can go to "User written body" which causes DI Studio to generate the macros (all of the macros, not some of them) but not the body of the transform. Or you can go to all generated. We put a requirement in to consider additional options for the future.
