Indeed, forces are not implemented for hybrid functionals. Also not for SOC. So, no relaxation of atomic positions is possible.

so much the better it is very cold here !!! (correct me if I am wrong) relaxation of atomic positions is possible only for functionals for which the forces are calculated correctly (GGA, GGA+U, onsite hybrids). This is not the case with spin-orbit coupling or the full hybrid functionals.
