Can't override Movie Graph Config variables in shipping builds

We are moving to Movie Render Graph. I’m trying to override some variables (filename, warm-up times, file type) to a Movie Graph Config. I’m using UMovieJobVariableAssignmentContainer to override variables without updating the Movie Render Config asset, but I can’t seem to get it to work in a shipping build (works fine in the editor). It seems like the problem might be this in MovieJobVariableAssignmentContainer.cpp:

#if WITH_EDITOR

void UMovieJobVariableAssignmentContainer::UpdateGraphVariableOverrides()

#endif

Is there a way to get around this so overriding variables works in shipping builds?
