Oracle VM 3.3 on R630

It appears that the R630 is certified with Oracle VM 3.3 (linux.oracle.com/.../f).

However, the documentation for Oracle VM 3.3 states that VT-d must be disabled in the BIOS (docs.oracle.com/.../vmrns-server-bios-setting.html).

I only see an option to disable "Virtualization Technology".  If I disable this then VT-d gets disabled but VT-x also gets disabled so I can't run any HVM or PVHVM guests.  Is there a way around this?
