Do you organize large meetings or present material in them? To avoid random noise and visual distractions, you can disable attendee mics and cameras. Then, when you want someone to speak or be seen, you can let them turn their mic or camera back on.

Note: Currently attendees who call in to a meeting using the phone number provided in the meeting details won't be prevented from turning on their mic and camera.

For info on which meeting participants are classified as "attendees," see Roles in a Teams meeting.
