It is confirmed that if the Laptop only requires 45 W or 65 W power, that you can do this setup =
Laptop TB/USB Type-C out port --> P2720DC USB Type-C to C cable --> P2720DC USB Type-C in port (Menu- Display- MST On) P2720DC DP out port --> P2720DC DP to DP cable --> Second monitor DP in port
All, the P2720DC cannot deliver power to laptops that require 90w or higher. See page 29.

About the PD of the Laptop. I thought the monitor is capable of delivering the power to the Laptop, isn't it? So I plug each of the monitors to the power supply and use the P2720DC USB Type-C PD to charge the notebook and simultaneously transfer the video signal.
On the product page, it is shown, that a laptop is only connected via one cable to the screens (link below). In total I thought the following set up:
Screen 1 in the daisy chain P2720DC: Connected to power (connector 1 in the connector schematic - link below) and USB Type-C from the Elitebook to the monitor, to "just" broadcast the video signal for both screen and data to a mouse and keyboard via the USB Type-C cable.
Screen 2 in the daisy chain P2720D: Connected to power (Connector 1 in the connector schematic) and via display port connect it to the first screen.
About the daisy chain uncertainty via USB Type-C. If this is not the case, then the pictures in the above link are misleading, since the USB Type-C connector is the only one, capable of providing power to a laptop and the pictures clearly show, just one cable connected to the laptop and two screens connected.
I found a dealer nearby, I will contact him and ask, if I can bring my laptop and try my proposed solution. I will post my experience. Might take 1-2 weeks.
