ciphers: an array of allowed cipher suite strings in BoringSSL format (e.g., ["ECDHE-RSA-AES128-GCM-SHA256", "AES128-GCM-SHA256"])
min_tls_version: a string indicating the minimum TLS version — one of "1.0", "1.1", "1.2", or "1.3" (e.g., "1.2")
http2: a string indicating whether HTTP/2 is enabled — "on" or "off" (e.g., "on")
