TLSv1 should be disabled

You currently have TLSv1 enabled.
This version of TLS is being phased out. This warning won’t break your padlock, however if you run an eCommerce site, PCI requirements state that TLSv1 must be disabled by June 30, 2018.

Any way to get TLS v1 disabled? The certificate verify got a B grade instead of A because of this.
