You can't, especially if you're using 'rebar3 shell', where all we can do
is boot a shell within an escript. Do try to debug from a release. You can
probably do something like

cerl -boot _build/prod/rel/<relname>/release/<version>/<relname> -config
_build/prod/rel/<relname>/release/<version>/sys

or if possible:

_build/prod/rel/<relname>/erts-<vsn>/bin/erl -boot
_build/prod/rel/release/<version>/<relname> -config
_build/prod/rel/release/<version>/sys -emu_type debug

These two commands will ignore the contents of your vm.args but they let
you call the underlying mechanism to boot the VM with the arguments you
need without the nodetool wrappers that relx ships.
