How do I set the default reference attachment of Drawing Boundary to None? I've looked in Preferences and the option under the configs but can't locate this.
No sure if you are asking about the option to set Drawing boundary to none in the case of attaching a reference to a sheet model. If that is the case you can just select none from the Reference attachment dialog.
if this is not what you are looking for please send a screen shot or elaborate a little more.

Agreed. Never notice it on placement. Then I go to cleaning up a file and find these annoying callouts in the middle of nowhere.
