running schedueled tests from TFS 2017

Question

I have an established project in TFS 2017 with several build definitions.  I have been looking into automating the running of these builds on a nightly basis.  However upon further reading it seemed that first I needed a test plan, but in order to have that I need to sign up for VSTS and create a backlog. 

I already have my team project with my builds setup.  All I want to do is schedule my existing builds to run at a certain time of the day.  Do I really have to sign up for a VSTS account and create backlog items in order to achieve this in TFS 2017?
