Is there anyway to host an Heygen Avatar Model locally?

Hi, I'm using the paid version.

Because of my client's unstable internet connection, sometimes the avatar will be disconnected. I just want to use the speak function with a predefined text, without voice chat, and only use 1 model.

Is there any way I can self host a model locally so that I can serve them together with my web app?

Any help would be really appreciated.

Thanks HeyGen team!
