Firmware patching with OME

Hello,

I used Dell OME 1.0 in a previous workplace, and have recently setup 2.0 in my new workplace. My question is, what firmware updates can be made through the iDRAC? Seems like OME is only seeing the BIOS and iDRAC firmware updates, and not the RAID controller, MB, NIC etc ... For security purposes, I would like OME to be able to make all updates via the iDRAC, and not have to setup SSH discovery to each host with a static/privileged account. 

Is this possible ?

Thanks!
