intel mpi 2019 - I_MPI_PROCESS_MANAGER I_MPI_SHM_LMT mpiexec.hydra replacement

Hi,
I am using intel mpi 2019 to run few applications. 
i get following warning messages during start of the run - 

[0] MPI startup(): I_MPI_PROCESS_MANAGER environment variable is not supported.
[0] MPI startup(): I_MPI_SHM_LMT environment variable is not supported.
[0] MPI startup(): Similar variables:
I_MPI_SHM_OPT


A)
Is there a way to supress these unsupported  environment variables messages?
B)
What would be the replacement of these 2 outdated variables ?.
Currently i am using - 
I_MPI_PROCESS_MANAGER = hydra
I_MPI_SHM_LMT = shm

is the following equivalent  - 
unset  I_MPI_PROCESS_MANAGER   
unset I_MPI_SHM_LMT
I_MPI_SHM_OPT = shm


I plan to set these up in shell scripts ( before mpirun) as i dont have permissions to remove these variables from the main module file.
c)
Also, can i replace 
mpiexec.hydra with mpirun ?

- puneet
