Windows 10 build deployment through group policy not WSUS

I'm trying to get some details on how to deploy the latest build (or 1703 will be fine) of Windows 10 to my company's workstations using Group Policy instead of WSUS.  The systems are utilizing WSUS pushes but only for security patches and updates to the current build.  In order to use Windows Update, I'd have to take all of these systems off the WSUS solution.  Trying to avoid that complexity, but running into another.  My WSUS admin doesn't want to hassle with whatever it would take to push builds via WSUS and says that this can be done by using Group Policy, but won't give me how-to.  I'm not that experienced in Group Policy, so I was hoping that someone would have some great instructions for me to follow.  Thanks for any feedback you can provide.

Put the ISO on a share. Use GPOs to deploy a scheduled task that runs the upgrade setup. as in
