Interesting question Cecil, and I suspect the answer is yes
if you are refering to the array pointing upwards.
If you are referring to turning the array sideways i.e vertical
polarisation then I doubt
rear radiation could be zero because the earth has more influence over
vertical
polarisation compared to horizontal at one wave length high.
For instance pairs of elements could not have equality.
You can ofcourse accomplish such if the array was reflective as with a dish
but not with normal coupling and resonances where the focussing aproach
is absent.
Best regards

If the phases and and magnitudes of the paired elements
are exactly the same, then radiation to the rear is zero.

If you rotate the elements by 90 degrees, can you make the
radiation toward the ground zero?
