U2723QE, DDPM, Command Line (CLI) syntax, PBP Mode?

Hi everyone!

Recently got a U2723QE and was excited to use the CLI to switch some monitor states. I'm finding some commands work, some do not. I'm wondering if syntax is an issue. The documentation is as follows:

/Applications/DDPM/DDPM /1:WritePxPMode Off

This turns the current PiP off.

I would expect one of:

/Applications/DDPM/DDPM /1:WritePxP PBP USB-C HDMI

/Applications/DDPM/DDPM /1:WritePxPMode PBP USB-C HDMI to turn on PBP with USB-C on the left, and HDMI on the right. However it doesn't work. I have also tried 'split' in place of PBP.

Here is Dell's documentation from the DDPM folder:

==============================================Dell Display Peripheral Manager==============================================Support Mac:Mac 2018 or above.Support OS:macOS 11 or above.Setting Up:Connect your Mac to monitor by display cable or USB upstream cable. Dell Display Peripheral Manager uses DDC/CI channel to communicate with your monitor. Ensure DDC/CI is enabled in the monitor On-Screen Display (OSD) menu.Grant Security Permission: - Requires Accessibility privacy permission to allowDell Display Peripheral Manager for Easy Arrange andEasy Memory functions.- Requires Automation privacy permission to allow Dell Display Peripheral Manager for Easy Arrange and Easy Memory and Command Line functions.- Requires Camera privacy permission to allow Dell Display Peripheral Manager for camera preview.Troubleshooting:If Dell Display Peripheral Manager is unable to detect and/or communicate with a supported Dell monitor, please take following actions to troubleshoot:- Make sure the video cable or USB upstream cable is properly connected to your monitor and your computer. Ensure all the connectors are firmly inserted into the ports.- If connecting HDMI cable not working, switch to use HDMI and USB upstream cable. Launch DDPM again.- Check the monitor OSD to ensure DDC/CI is enabled.Input Manager-----------------------------------------------The Input Manager tab provides convenient ways for you to manage multiple video inputs connected to your Dell monitor. This makes it very easy to switch between inputs while you work with multiple computers.Easy Arrange-----------------------------------------------Easy Arrange tab simplifies the applications window organization on the monitor.Window Snap-----------------------------------------------Application Window Snap is designed to enable application placement on any screen quickly. When the application is on the connected monitor, dragging the application triggers easy arrange flyout menu, you can drop the application to any of the recently used layout quickly.Auto Mode-----------------------------------------------Dell Display Peripheral Manager automatically switches to the corresponding Preset Mode whenever the associated application is activated.Shortcut Key-----------------------------------------------Enable combo keys to make actions such as calling up DDPM, Easy Arrange, Window Snap, Favorite input...etc.Power Nap-----------------------------------------------You can choose to set the brightness of the monitor to the minimum level, or to put the monitor to sleep when the screen saver is activated.Command line Interface that DDPM supports-----------------------------------------------A rich and flexible command language is supported via thecommand-line, and command-line arguments can be combined.Where appropriate, a specific display can be targeted byprefacing the command with the enumerated display number, e.g., "2:AutoSetup"; if the enumerated number is not specified the command will be applied to the current selected display or to all displays, as appropriate.
