P4k Raw clip settings to higher than ISO 1600 in Resolve

So I visited a Blackmagic exhibit here in Texas today and I asked the BM guys there, but they don't have info on my question.
We know the new BM Pocket 4k can go up to 25600 ISO and shoots in Raw. I got a BMP4K footage both in CDNG and BMRAW but when I open them in the latest Resolve 15.1.1 in the camera tab, when I select CLIP, the ISO option goes up to only 1600. How can I change this to a higher ISO if this is a RAW file?

edit: I found that the BM raw clip is not from the pocket. But the CDNG clip i have downloaded from the BM site is of the mountain bike clip.
