Specify the proposer configuration file using the [`--validators-proposer-config`](../../reference/cli/index.md#validators-proposer-config) command line option.

 In this example, the builder is enabled by default, with `timestamp` registration override. Each validator has its own `public_key` override. All validators use the same `0x6e35733c5af9B61374A128e6F85f553aF09ff89A` as `fee_recipient`.
