Hi there Rath, I use a Trezor Hardware wallet. I'm not sure if they implement CPFP.
Unfortunately, the Trezor web interface 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 (if you are using Windows or OSX, download Electrum directly from their website). 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.
I think this can be a typo error. Which supposed to be Child Pay For Parent.
Yeah, it is a typo. Thanks for pointing it out!
Also, I think the best option to still recommend should be replace by fee (RBF), although I think which the OP said the fee for accelarating the transaction is too high.
RBF can be used only by the sender.
