Cipher Suites for Windows Server 2008 R2

I want to add below cipher suits in my Windows Server 2008 R2 SP1 Standard as required by our security team. As per my research (see below links) these cipher suits are not supported by Windows Server 2008 R2 and are only available in Windows Server 2016.  Can someone conform me this? Also please let me know if there is any possibility to use these ciphers.

First 2, not at all. Next 2 appear like they're supported.

The last 4 appear to be within 2008R2, under the section of being supported by Schannel but not enabled by default. However, you'd also have to get ECDSA certificates for those to work.

Thanks for your response, how can I check if my existing certificate is ECDSA or not?
Chances are they are not. I would recommend simply checking with your certificate vendor.
