Another idea similar to Ian's (5)-- if the footprint's pads don't work well
(e.g., it's a large footprint with pads around the edge), you could add tiny
(zero size?) free pad(s) in the interior, put them into a pad-class, then
use a via/pad-class clearance rule.  Unfortunately, the pads will probably
interfere a bit with tracks being routed through as well.

Or possibly:

6) Place one or more buried vias within the footprint; depending on the
shape of the area to be excluded, you might still need a design rule, or
possibly just make the buried vias large enough/close enough so the router
can't get a normal via in there without violating your standard via/via
clearance.  The buried vias won't interfere with track routing.
