How do I get the cheapest possible transaction fee using Trezor suite

I’m new to crypto & Trezor suite so when I use it I see that the transaction fee is 7% of the entire Bitcoin purchase through the exchanges Trezor works with.

Is there a way to circumvent the high fee or a setting I need to toy with on Trezor suite?
