How to setup mainnet archival Node

Hi team, We followed the documentation: https://network.fetch.ai/docs/guides/ledger/installation to setup our own mainnet node. 
We see that the steps available are either for **testnet** or **validator** node(Needs a wallet)
Is there a way to setup a **MAINNET** **archival** node from genesis, with or without snapshot, without requiring a **wallet**?

Thanks,
Mahendra
