How to setup TTD for consensus layer?

[shijie0]

Hi there, may I check how to setup TTD for consensus layer on mainnet? According to the release page, terminal total difficulty (TTD) for Ethereum Mainnet is added in version 2022.08.02-alpha.

I'm using erigon version:
OS: ubuntu 20.04

erigon version 2022.08.3-alpha

consensus client:
beacon-chain version Prysm/v3.0.0/1c6fa65f7b8bb7fea54fd82d0ef07960b460c45a. Built at: 2022-08-22 20:36:41+00:00

But I get the following error message:

Sep 05 05:59:21 ip-10-13-14-124 erigon[1391033]: [WARN] [09-05|05:59:21.487] Served                                   conn=127.0.0.1:39088 method=engine_exchangeTransitionConfigurationV1 reqid=3917 t=70.923µs err="the execution layer doesn't have a terminal total difficulty. expected: 0xc70d808a128d7380000"

Any ideas on how to solve this issue? Thank
