Set the trap before the lines in question, and remove it afterward.
trap: trap [-lp] [[arg] signal_spec ...]
[...]
ARG is a command to be read and executed when the shell receives the
signal(s) SIGNAL_SPEC. If ARG is absent (and a single SIGNAL_SPEC
is supplied) or `-', each specified signal is reset to its original
value.
