I've found a way to disable warnings for an entire VB.NET project, but that is very undesirable. I would like to disable a certain warning for the scope of one method at most. A line-by-line disable and restore would be better. For example, C# has #pragma warning disable (and restore). Does VB.NET have anything like this?
If you are using Visual Studio 2015, the answer is yes, yes it does. The syntax is #Disable Warning BC40000 and #Enable Warning BC40000

Unfortunately the answer is no, the VB.NET compiler doesn't support suppression of warnings in such a manner. You would have to re-factor your VB.NET code or look at some other alternative like writing some of the code in C#.
