Check the OMSA command 
omconfig chassis biossetup attribute=bootorder sequence=<list>

The sequence of boot devices will be enabled in the bios and the devices
that are not part of the sequence will be disabled.

Subject: disabling boot devices on poweredge servers?

The syscfg utility provides a mechanism to change the default boot 
order, but I would like (for security reasons) to disable boot from USB 
or CD-ROM (I can turn off PXE boot from the NICs).  I don't want to use 
a BIOS system password (as these are servers and need to be able to 
reboot unattended) but will enable a BIOS setup password to lock in the 
changes once they are set.

I can see how to disable boot devices in the F2 setup screen, but would 
like a way to do this programmatically, without running Expect on a 
DRAC/BMC serial console session.

Any suggestions?  Is this possible using OMSA?
