I've removed or disabled EGR on a number of engines in my day. Disabling can be as simple as the ball bearing idea or cutting a tin can to the shape of a gasket (but with no hole in it) to block the gasses off. Removing the system and fabricating block off plates is usually my preference, as it really cleans up the engine bay. Really depends on your skill level and the time you have. If you do remove the whole system, be sure to block off the vacuum source line properly.

And the idea of not JUST blocking off the vacuum line and also using a blocking plate is that the butterfly valve might not be closing completely?

The idea is if you remove all the vacuum actuators (VSV's), you no longer need vacuum routed to them. Remember that your vacuum pump is the source of all vacuum. Vacuum is used for emissions systems, the brake booster, and the transfer case vacuum engagement (4x4). So if you remove the emissions VSV's, you need to cap off the vacuum line that used to supply them. If you simply block of the EGR gasses, but leave all the VSV's, you can just leave the vacuum lines as they were. Doesn't matter if the EGR valve opens or closes, no gasses will get through at that point anyhow.

Got it - thanks for the explanation. I guess that a better way to phrase my question is “can an EGR delete be accomplished by only blocking your vacuum line so that the butterfly valve would never get actuated to open?”

It is possible to force the actuator to keep the EGR in the closed position. This can be done by switching vacuum lines around at the actuator and unplugging/bypassing the electrical part. Read the manual to figure out which position is which etc. It's possible however that the EGR valve is no longer working at the vintage your engine is at though. They do get really coked up.
Easiest thing is probably still just a physical block off. Then you don't really have to think about it.

Thank you so much for taking the time to explain this - I appreciate it!
Lomo has me convinced that I really should be taking off the intake manifold to “degunk” anyway!
Thanks again!
