Hello,
It is stated that:
Teams is always conservative on bandwidth utilization and can deliver HD video quality in under 1.5Mbps.

If you want to ensure that Teams is receiving the proper bandwidth you will need physical network equipment that handles QoS (Quality-of-Service) and ensure that you prioritize Microsoft 365/Teams traffic (if you have bandwidth constraints).
