Answer
UCS does have the option to specify the number of cores in the BIOS Policy in Advanced, Processor, the option is called Core Multi Processing.
To make the change you need to create a new BIOS policy only to be used by the Service-Profiles assigned to the servers where the cores are to be manually specified.
Create the new policy and copy all the settings from the old policy and make the change to the Core Multi Processing option. Then set this as the BIOS policy to be used by the required Service Profiles.
Or if you already have a BIOS policy used only by the required Service-Profiles then you can edit it.
See example below, the change was made to the SRIOV BIOS policy.
The option to change is in Advanced, Processor, Core Multi Processing.
The number of cores is set to 6 which will give 12 cores total (For blades with 2 CPUs)
