Server 2012 R2 IIS Cipher TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256

Question

Hi guys

I am currently using Server 2012 R2 and IIS as the web server.

I need to update and enable the cipher to use TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256

but when I use the nmap to check the cipher it was not there.

Can I post the question to MSFT community
May I know if I need to change my SSL cert or ?

Thanks in advance MSFT community
