Check the section in the controller's handbook about IFR altitude assignments. They must either be published or comply with 91.177.

Any provisions to the contrary would have to have a VFR restriction, which is not an IFR altitude assignment.

I don't believe that is correct. ATC cannot give you vectors below the MVA (the minimum vectoring altitude).

But you can still fly IFR visually maintaining terrain separation. Then ATC can clear you if they have no traffic conflicts. However you still have to remain more than 1000 ft above flatlands or 2000 ft above mountains--including the antenna. So, by doing this you might still be in violation of the FARs, but I doubt anyone cares.
