Does Dgraph support TLS 1.3?

I don’t know exactly how TLS works and maybe the question might not be well formulated. In the TLS Configuration of the Docs, it specifies the following:

To further improve TLS security, only TLS v1.2 cypher suites that use 128-bit or greater RSA or AES encryption are supported.

So, I’m not sure if I can infer from that that Dgraph only supports TLS v1.2? Or instead, can Dgraph work with TLS 1.3?

Currently I am doing some volume stress tests and the results throws me a higher latency with TLS rather than without it. Maybe working with TLS 1.3 could lead to a better performance.

Thanks in advance
