When you share your screen in Zoom, there is an advanced screen sharing option. When you click Share Screen, at the top of your sharing selection window there is an Advanced tab.

Advanced Share Options

The Advanced share shows additional options:

• Portion of Screen Allows you to share just a portion of your screen. When you start sharing, it will display a color rectangle that you can move around and re-size to share just the portion of the screen defined by that rectangle.
• Computer Sound Only Lets you share only the audio from your computer without actually sharing your screen. For example, you might want to play an audio clip, but not share your screen.
• Content from Second Camera Lets you share content from a second camera that is not your computer screen.   

In addition, Zoom lets you share screens from multiple participants. Zoom recommends the multiple share only be used when your participants have dual monitors set up. Learn how to set up multiple screen sharing.
