M-x apropos RET path RET

I'm sure you will find the variable you want.  Then a quick grep in
the emacs sources will let you find whether it is ever updated after
launch.  Then you may either locate the right command to update it, or
if there's none, you can write one.  By the way, if you scan the whole
apropos buffer, you might also find a function that would be useful
if you had to implement that command.
