Yes! There is a separate privacy setting for the Auto Route Generator.
First, head over to your Raider.IO account settings and then go to User Profile in the bottom left corner.
From here, you'll get to your user profile. On this screen, you can go to the drop down menu to allow anyone to see your routes, or just the players that were in the run with you. Be sure to hit save at the bottom of this window if you've made any changes.
