I don't think that's possible, is it? As you deplane in T3, you are automatically forced to go through immigration + customs. OP's connecting flight is Latam domestic from T2, hence no lounges there (although there is a Bradesco credit card lounge hidden in T2 airside, where Centurion members may be granted access but I didn't try a couple of days ago).
