Homestead "Checking if up to date" How to Disable??!!

This has been annoying me very much. I cannot find how to disable this. I added "config.vm.box_check_update = false" to the vagrantfile in the homestead directory, but it doesn't make a difference... when I run "homestead up" it still checks for updates. But if I run "vagrant up" in the same directory it doesn't check for updates.

Anyone know how to disable this for homestead?

Thank you
