To some extent, you can lower the fees in Ethereum blockchain and get the coins at a slower pace spending less amount of transaction fees but if they are much lower (in gwei) which  isn't getting a hit by miners, your transaction would be pending for hours and rejected. The best way to spend less is to check the current gas fees and use a fee that's just above the minimum required for going through. Use a gas tracker like https://etherscan.io/gastracker and go for a fee Low.
