mouse controls should be located under tools tab... then customize... then interface.... in there you should find the mouse settings...
That setting will need to be customized in your mouse driver software, if that is an available option. For instance, Logitech's SetPoint software allows many custom configurations that can either be applied to all programs or specific programs, such as AutoCAD. On my version of SetPoint with my mouse, I'm still unable to customize the left or right buttons, though. A quick Google search for "customizable mouse driver" returned this. You might give it a shot or try looking for other customizable drivers for your mouse.
Is there no way in AutoCAD (not using a work around with mouse drivers) so change this setting? MMB as pan makes track pad usage impossible.

Trackpad? Which one and driver version are you using?
