By default all Murano Conductor configuration settings apply to Murano Agent. If you want to configure Murano Agent in a different way change the default template. It can be found here:/etc/murano-conductor/data/templates/agent-config/Default.template. Take a look at appSettings section:

        <add key="" value="%RABBITMQ_HOST%"/>
        <add key="rabbitmq.port" value="%RABBITMQ_PORT%"/>
        <add key="rabbitmq.user" value="%RABBITMQ_USER%"/>
        <add key="rabbitmq.password"
        <add key="rabbitmq.vhost" value="%RABBITMQ_VHOST%"/>
        <add key="rabbitmq.inputQueue"
        <add key="rabbitmq.resultExchange" value=""/>
        <add key="rabbitmq.resultRoutingKey"
        <add key="rabbitmq.durableMessages" value="true"/>

        <add key="rabbitmq.ssl" value="%RABBITMQ_SSL%"/>
        <add key="rabbitmq.allowInvalidCA" value="true"/>
        <add key="rabbitmq.sslServerName" value=""/>

Desired parameter should be set directly to the value of the key that you want to change. Quotes are need to be kept. Thus you can change "rabbitmq.ssl" and "rabbitmq.port" values to make Rabbit MQ work with this exchange in a different from Murano-Conductor way.
