Outlook 2013 clients - enabling modern auth in O365 for Outlook 2016

I am testing out office 2016 on 2 or 3 computers (everyone else is on 2013) and notice modern auth is disabled in our O365 tenant after I ran a powershell query.

Get-OrganizationConfig | ft name, *OAuth*

 If I enable this will it affect my 2013 Outlook clients?

I realize there is a registry key required to enable modern auth for 2013 and I am not pushing this out - my plan is to just roll out 2016 which connects automatically using modern auth.

Any advise appreciated.
