Need per-API / per-trace control to disable media uploads

[amaann2]

We’re using Langfuse via LangChain callback handlers (langfuse==2.60.8, langfuse.callback.CallbackHandler).

We came across an existing approach that allows disabling media uploads globally (for example, discussed here: https://github.com/orgs/langfuse/discussions/6179). That solution is helpful, but it doesn’t fully cover our use case.

In our setup, media gets uploaded automatically through the LangChain callback flow, and what we’re looking for is a more conditional / selective control:
• For some API flows (e.g. large PDFs), we’d prefer not to upload media
• For other flows (e.g. images for debugging), media uploads are useful
• A single global on/off switch makes it hard to support both cases

We’re hoping there’s a supported way to control media uploads per API flow / per trace / or based on payload size, especially when using LangChain callbacks.
