Teams Abusive behaviour on video calls
Zer0 Hello, there are many ways to secure the Teams environment, with meeting policies and messaging policies for example.
You can start by reading this.

For the specific issue though you can turn off "anonymous can join meetings" (also described in above link) or adjust the teams meeting options (lobby and roles).

Is there a way to disable it per team via a PoSH cmdlet?
Zer0 Hello, sorry for the late reply! I've been experiencing issues not getting notifications when someone replies to my posts. So I'm chasing them down manually.
If your org. choose to keep the "Anonymous users can join a meeting" enabled, which is a Teams Meeting setting, you must ensure that the meeting organizers are using proper lobby settings. It can be controlled with policy or per-meeting using the meeting options (meaning you don't control the anon meeting setting but instead use lobby settings so anon users cannot attend).
It's described in detail here https://support.microsoft.com/en-us/office/keeping-students-safe-while-using-teams-for-distance-learning-f00fa399-0473-4d31-ab72-644c137e11c8?ui=en-US&rs=en-US&ad=US#ID0EBBAAA=For_administrators under "Prevent anonymous users from joining".
