How to ignore template files when assembling sass?

Hi all, there is this structure:

Files from folder templates added to the main.scss using @import.

Question: how to make during compilation I had in the folder dist/css only the file main.css?
This option ignores the Tusk is not suitable, because I have many nested pages, which will be your main.scss.
gulp.task('sass', function () {
 return gulp.src(['src/**/*.scss, '!src/**/*_.scss'])
