Is it possible to only upload dialogflow agent to a raspberry pi?

I'm uploading an agent I've been working on to a raspberry pi, but I'm wondering if Google/ dialogflow offers the same type of option as AWS where you can upload your own personal agent from AWS Lex without Alexa ( In this case, Dialogflow agent without the Google Assistant). If this is possible, how would I go about this?

Also, I guess if adding just your agent is possible, could you then set a custom "awake" phrase for your Dialogflow agent? So for example, could you just say "Hey CoffeeBot" (or whatever) to invoke it?

I'm new to the whole raspberry pi setup so if I'm completely mistaken by all of this please let me know!

Thanks for your help!
