can we integrate external LLM, TTS or STT providers with D-ID Agents?

Most of the posts here that mention this are a bit outdated (8months+) and were asked around the time D-ID Agents were publicly introduced so wanted to check if anything has changed since then. Are we now able to integrate external LLMs, TTS or STT providers with D-ID Agents? If so, what are the steps to do this? And if not, will this capability be available in the near future and when?
