[BIOS][ROG STRIX B450-I] Controls not available for AIO_PUMP header

[Sintel]

Recently build an ITX system based on the NCASE M1 & this motherboard - summary
- I don't have an AIO cooler
- I need all the fan headers I can get (5 fans)

Now I learned the AIO_PUMP header can be used to connect fans to - by default you don't get any control over the fan curve, which I understand.
- I changed the "AIO PUMP control" option in the monitor section from "Disabled" to "DC" (case fans are 3-pin).
- Now a default curve is applied which goes somewhere from 50% at 30°C to 100% at 55°C CPU (or similar, not in front of the machine)
- The problem is there are no controls available for this curve, while for other ROG STRIX motherboard models there is (I found screenshots online)

This is a screenshot of Z270I where the controls are present: https://imgur.com/ebojrWe
In the bios of the B450-I - these controls are NOT present. Is this a bug, is there a possibility this feature can be added in a future update?

Build info: my setup is very similar as this one https://imgur.com/a/xfJ3R#oxQY0zH
The main difference is I'm also using a ROG STRIX GPU (a handover from previous build - RX-480-O8G) + 2*120mm fans in the bottom

Just checking in on you here. Did you ever get the controls to be visible in your BIOS? I have the same board and I see them. Maybe a BIOS update fixed it.
