Needed to add Infura priority fees for Avalanche and adjust existing ones due to the credit amount.

Used this example for fee calculation:
trezor/trezor-suite#17781

If I understand this correctly, Avalanche is now configured to use Infura's gas API. If Infura does not support chain ID 43114, the alternative fee provider will never return data. Because EthereumTypeGetEip1559Fees short-circuits to the alternative provider when configured, this results in nil EIP-1559 fees instead of falling back to the on-chain estimator.
