Using Raw Signing with Private Besu Network

We are evaluating a private Hyperledger Besu EVM network in our Fireblocks Sandbox workspace. Besu is not available as an asset/network in the Vault UI.

We understand that Raw Signing is enabled by default in Sandbox. Can we use Raw Signing with an EVM signing wallet/address to sign transactions intended for our private Besu chain? If so, what is the recommended way to create/use the EVM wallet for this purpose?

Thanks.
