Upload instructors .csv without triggering a 'User has been created (by administrator)' notification

Hi there, 

I know how to add someone manually and switch the toggle so that they don’t receive a ‘welcome to the platform’ email. But I want to know how I do this via a .csv file. I want to upload 30+ instructors, but not have them notified as we’re new to the platform and want to have a virtual meeting to walk them through their dashboard. 
I want to upload them so I can assign them into Groups, PowerUser Mgmt, Learning Plans, etc. Here’s my .csv, do I need to add a field here? 

Or is there a completely different method that I need to do that has nothing to do with a .csv?
 

Thanks for your help!
