npgsql driver sslmode missing verify-ca and verify-full -- PostgreSql

As per links below, PostgreSql supports several ssl mode connections, but its ADO.net driver, npgsql does not support the modes verify-ca and verify-full, which are supported by the its JDBC driver.

Is there any reason for this? Is it possible to use these modes somehow else?

Npgsql will by default verify the server certificate, so SSL Mode=Require would correspond to libpq's verify-ca or verify-full (the documentation is not entirely clear on that).

From the documentation link in your question:

By default, Npgsql will validate your server's certificate; if you're using a self-signed certificate, this will fail. You can instruct Npgsql to ignore this by specifying Trust Server Certificate=true in the connection string. To precisely control how the server's certificate is validated, you can register UserCertificateValidationCallback on NpgsqlConnection (this works just like on .NET's SslStream).
