Yes, a covalent network crystal with sp3d2 hybridization can potentially form a 2D solid. However, it would depend on the arrangement and bonding of the atoms in the crystal structure. The sp3d2 hybridization allows for a variety of bonding geometries, including those conducive to forming two-dimensional structures, such as sheets or layers of atoms bonded covalently in a planar fashion.
