Thank you for your patience while I looked in to this for you. If you go in to the device specific settings of the XR, then go to Port Configuration> Change the Connection Type to PPoE and create a PPoE Profile, that should enable PPoE on that port. For example:
You can also add firewall rules to the device template by going to Configure> Open the Network Policy> Go to the Router Settings tab within the Network Policy> Scroll down to the user profile settings in the port configuration section> Create a new user profile> Enable firewall rules> Create the firewall rules you want to apply.
