As the title says, a crystal that is electr-optic and pyroelectric can it be non-birefrigent?

No. Pyroelectric, piezoelectric, etc. crystals do not have inversion symmetry (or else they would not by pyroelectric, ...). This reduced crystal symmetry implies that the axes are not equivalent, so birefringence will occur.
