Is there any way to force the MacBook to use the dedicated GPU, and therefore forcing PoE to do the same?

Under system preferences, go to battery then click the battery section. If you have discrete graphics on your mac, you will see "Automatic graphics switching". Uncheck that.

Click the apple logo, and go to About This Mac...under graphics, you should see both the integrated and discrete options available.

Not sure if apple regards the discrete graphics as a card.
