No, you cannot select different networks to know the fees. Ethereum is the primary network used for fees and it is based on the Ethereum Virtual Machine (EVM). The fees for Ethereum are determined by the miners, who decide the amount of gas (transaction fees) they will charge for each transaction. The amount of gas is determined by the amount of computational power needed to process the transaction. The higher the gas amount, the higher the transaction fee. Additionally, different networks have different fee structures, so it's important to understand the fees associated with the network you are using.
