Partitions on brand new Dell BOSS drive?

I went to install Windows Server 2022 on a brand new Dell R360 with a BOSS card and it shows up as having a couple partitions on it already: ESP and OS. Are those partitions supposed to be there? What are they? Do I have to keep them or can I delete them? The system was specced without an OS.
