Of course (at least as far as Earth is concerned).
Earth receives a stream of entropy from the sun via solar radiation
(approximately the energy of the solar radiation impacting Earth divided
by the black-body temperauter of the Sun) and emits entropy into space
via radiation, approximately the same amount of energy from the sun
divided by the temperature of Earth as a black body. Because that
temperature is much lower than that of sunlight, Earth generates
a lot of entropy.
The Second Law states that the change in entropy of any system has
to be larger than, or equal to, the sum of the entropies going
over the boundariy of that system. So yes, the Earth's entropy
could decrease, by quite a lot.
