You can use the Ugreen USB C to DisplayPort cable (product ID: 25157) to connect your MacBook Pro to an HP display without the need for a docking station.

Here are the details:
- The cable connects devices with a USB-C or Thunderbolt 4/3 port (like your MacBook Pro) to a monitor with a DisplayPort connector (like your HP display).
- It supports DisplayPort 1.4 and offers up to 8K @60Hz resolution, providing a clear and stable connection.

So there is no need to use a docking station or adapter in addition to this cable as long as the appropriate connectors are available.
