Driver and Firmware MSI suppress reboot in SCCM deployment

I am trying to deploy various Surface Driver and Firmware MSIs through SCCM. However during the deployment the MSI initiates a restart with only one minute timeout.

Is there any way to suppress the reboot and let the SCCM client schedule the reboot with an appropriate 15 minute countdown etc.

I tried with a /norestart parameter but that did not change the behaviour. 

Right now I am starting the MSI from a script and issue a shutdown /a after completion. From that point SCCM client is scheduling the timeout. It seems like a dirty solution and I would like to know if there is a better way of doing it.
