The second option is to blur the background
The other options are different backgrounds
Microsoft allows users to upload customized backgrounds to use during video conferences.
To upload a custom image via the Teams desktop client, access the Apply background effects option in a meeting and click Add New.
If you want to remove an image, simply hover over the image you want to remove and click the trash can.
