display-popup-menus-p is supposed to be a capability-reporting
function, like display-graphic-p.  It shouldn't be customizable.  What
should be customizable are the Lisp programs which ask questions via
popup menus.  The function you mention, read-multiple-choice, already
allows that via the existing variable use-dialog-box.

Btw, the dialog/menu should only pop up if the command itself was
invoked via a mouse.  Since you say you don't want to click the mouse,
I wonder how come you got that popup menu in the first place.
