Internet speed prioritization in containers

How can I prioritize a container with regards to internet speed? Let’s assume I’ve got two podman (docker) containers and both upload stuff.

Reasoning

My upload bandwidth is limited. One container needs to reliably upload stuff and the other doesn’t. Thus, I want to prioritize one container over the over in order to deliver content in this container reliably.

Example

Syncthing can sync over a long time period but jellyfin can’t.
