How to force TLS 1.2 for vCenter 6.0 & ESXi 6

Hi,

We are planning to upgrade a secure environment and a requirement is to only use TLS 1.2. I have been reading 6.0 U2 and that supports 1.0, 1.1 and 1.2. How do I disable 1.0 and 1.1 then only ensure 1.2 is used for this virtual environment.

Thanks
