There is no way to disable the last scf step from input. You may easily do
that by modifying PW/src/move_ions.f90: change lines 153 and 160 to
ions_status = 0
and the code will not execute the last step (neither the one with nonzero
magnetization nor the one with the final cell).
Note however that you cannot run a non-scf calculation starting from the
data of the variable-cell optimization and that convergence trouble in the
last step won't go away in a new calculation.
