'Is there an environment variable to force multithreading for IntelMPI on Linux?

MPICH and OpenMPI both are implementations of MPI and have each an environment variable, respectively MPIR_CVAR_DEFAULT_THREAD_LEVEL and OMPI_MPI_THREAD_LEVEL, to force the level of thread support, even when the initialisation is done through MPI_Init and not MPI_Init_thread.

Though this is going against the MPI norm, this is extremely useful in a lot of practical cases.

I've gone through the IntelMPI documentation (here) to try and find the equivalent variable in IntelMPI but came back empty handed.

Does such a variable exist in IntelMPI? Have I missed it?

Thank you for any help.
