Installing an integrated handlebar

Fitting one of these on my bike:

Bike is a Cube attain gtc pro disc 2017. Bars do not currently have integrated cables.

However the frame does, both for the disc hydraulics and the gear cables.

Is there a most straightforward way to go about this? Shifter cables will have to come out completely right? Can the disc hydraulics just get unscrewed from the shifters and stay where they are in the frame?
