You can't turn on points for objects that are made up of more than one joined surface that are joined at trim edges, which will usually be what you get as the result of a boolean.

But you can use Edit/Separate to break your joined object into individual separate surfaces, and then you should always be able to turn on control points for an individual surface that is not joined to another one.

That's what I did to turn on control points in those screenshots I posted previously.

Please check out this for some better explanation and illustration of why it doesn't turn on points for joined trim edges:
