WinSCP .NET assembly directory list timeout

Question

When there are many files in the remote directory often have session timeout problem, what's the default session time and if increase will be any side effects?

var allFiles = session.EnumerateRemoteFiles(folderIn, null, EnumerationOptions.None);

Part of the error logs:

Timeout waiting for WinSCP to respond    
    at WinSCP.Session.CheckForTimeout(String additional)     
    at WinSCP.PatientFileStream.Wait(Int32& interval)

    at System.Xml.XmlTextReaderImpl.ReadData()

    at WinSCP.Session.ListDirectory(String path)
    at WinSCP.Session.<DoEnumerateRemoteFiles>d__86.MoveNext()

WinSCP .NET assembly version 6.1.2

And any difference between the following two:

setup the timeout in SessionOptions and use it when open the session

var sessionOptions = new SessionOptions
{ Timeout = new TimeSpan(0, 2, 0) };

or 2) open the session then set the timeout value?

session.Timeout = new TimeSpan(0, 2, 0);

As documented, the default value of Session.Timeout is one minute: https://winscp.net/eng/docs/library_session#timeout
