Subject: FTP doesn't support all ciphers / signature hash algorithms and only supports

Our requirement to connect to FTP server with certificate using TLS Cipher Suite **ECDHE-RSA-WITH-AES-256-GCM-SHA384**.

But when I am trying to connect to FTP server with config **client.Config.AllowedCipherSuites = TlsCipherSuite.All**; 

I am seeing through Wireshark it only supports next ciphers during Client Hello handshake protocol:

And server closing connection because client doesn't support correct algorithm hash.

When I am trying to specify to use **ECDHE-RSA-WITH-AES-256-GCM-SHA384** as **client.Config.AllowedCipherSuites = TlsCipherSuite.ECDHE-RSA-WITH-AES-256-GCM-SHA384;**, then wireshark show no available signature algorithms.

I am using latest component pro version 7.2.238

Please let me know how to add support of other signature algorithms including **ECDHE-RSA-WITH-AES-256-GCM-SHA384**
