PSA E4440A: how to send VB direct I/O (SCPI) from IVI-COM?

I'm communicating with my E4440A using a IVI-COM driver and Visual BASIC  I'd like to use some commands apparently only supported using SCPI (e.g. SYSTEM:OPTIONS).  There is purportedly a direct I/O path-through method for these cases but I don't see any mention in the help guide nor any examples. 

Can anyone give me some sample VB code to do the above?
