You can always not connect the data wires to the port.

Then you can't use USB-PD protocol and only get the gimped resistor-based current negotiation.

USB-PD doesn't use the data wires (dp/dn or the two high speed diffpairs), it uses a sidechannel (CC). You can have a full PD implementation without a host controller or any data connection.
