It looks like there was reference to this in BedrockInstaller.php, but never actually fully implemented. I've added the parameter to the docs in ValetCommand.php, and updated the installer to replace the parameter.
The only thing that may need to be considered, is that this will un-comment DB_HOST across all installations, regardless of whether you customise the dbhost parameter or not.
