There is an option within the OpenVPN application that allows selection of a TCP-based connection, however if you find it becomes necessary to use TCP - we recommend using SoftEther or L2TP (L2TP is a TCP-based client offering flawless connection for mobile devices in particular).

You really don't want to have congestion control on your encapsulated connection and the underlying real connection. It actually would be fine for some workloads, but definitely not for streaming.
