How to disable TLS version prior 1.3 i.e. TLS 1.0 and TLS 1.2 on the Vercel next js site?

Hi @sitecorethinker, welcome to the Vercel Community!

Based on the Vercel Encryption Documentation, Vercel supports TLS version 1.2 and TLS version 1.3 by default for all deployments. However, you cannot disable specific TLS versions like TLS 1.2 on Vercel’s platform.

This is because TLS configuration is managed at the infrastructure level by Vercel’s Edge Network, not at the application level. The TLS termination happens before your Next.js application even receives the request.

For most use cases, having both TLS 1.2 and 1.3 enabled provides good security while maintaining compatibility with older clients. May I know what is the underlying requirement for this request?
