Unfortunately, the Trezor web wallet is quite limited. You will need to use Electrum instead. Here you can learn how to use Electrum with your Trezor without having to expose your seed. Once you open your wallet in Electrum, you should see "Child pays for parent" option once your right-click on the unconfirmed transaction in the "History" tab.

Hi there Rath, I use a Trezor Hardware wallet. I'm not sure if they implement CPFP.
