  Correct. It does not turn off setting solver options from the command line.

  It only turns off things like -ksp_view -snes_view -ksp_view_mat etc that one doesn't usually want in production runs anyways. The reason to turn those off is that they are checked directly in the solver routines such as KSPSolve(), the solver options are checked in KSPSetFromOptions() etc which are not called for each solve.
