If you destroy the segment, it is possible that it will damage other parts
of the display, though unlikely.  Most likely problem is that it may
'smoke' and leave a scorch mark somewhere visible.  IME, reverse voltage is
more likely to kill an LED without it getting so hot, that might help you!

However, why can't you just cut the DP wire on the displays where you don't
want a decimal point?  Or cut the track to the DP pin if they are already
fitted?  I think there's something you're not telling us, those
alternatives seem so obvious I suspect you've already ruled them out for
some reason :-)
