Hi, SistemasSanLucar, 
 
You may be able stop firmware updates from each Apple device itself, however it is currently not possible to block firmware updates from the SMC console. With the current version (5.1.3) you can restrict users to install apps but not the update of the phone's firmware or software. 
 
You can submit it as a feature request for possible implementation in a future version here:
