Internal PERC controller for my R440?

Hi, guys, this is my first topic, reaching from Argentina.

I just bought an second hand R440, and as I can see at Dell's documentation, it has an internal PCIe slot for internal PERC controller mounting. Refer ITEM 16: https://www.dell.com/support/manuals/en-us/poweredge-r440/per440_ism_pub/system-board-jumpers-and-connectors?guid=guid-a65bd6de-957d-4349-b7f2-c960c7a36a57&lang=en-us

The thing is that I couldn't find any Dell's doc listing wich PERC controllers modules can be installed on such PCIe slot. Actually, to be honest, every controller module I saw, has no compatible physical interface, according to the chasis presentation. Is it because I must use any adapter bord or wire, or what?

Perhaps I'm still a bit dumb on this, I must say that this is my first Dell server, I always worked with HPE.

Can anybody bring me any data, please?
