VTG can also be set through AVRDUDE, but only from "terminal mode"
(option -t).  As the startup will probe for a valid AVR ISP
connection, if you don't have a target connected to ISP (or if your
VTG is set to 0 for some reason so the target cannot respond), you
have to force it entering terminal mode by -F.

Once in terminal mode, use something like

vtarg 3

You should also be able to read out the current settings by


If there's enough demand, it would perhaps also be possible to add a
commandline option for it (through the -x "extended options" feature),
but so far, nobody seemed to care much about it.
