[CentOS] deleting selected partition in kickstart

I am trying kickstart for the first time, and am running into something I don't see described in the documentation.

Somewhere between me and my purchasing department and Dell, my order for 6 PE 1850s was changed from "no installed OS" to WIndows. So I received the boxes with Windows pre-installed.

I would like to delete the NTFS partition with Windows, but keep the Dell Utility partition on the first partition. In the documentation for kickstart, I see options for

deleting linux partitions deleting all partitions

but not one for deleting one or more specific partitions.

Am I right about this? Thanks,
