At first sight i didn't see an option to do this.
If you don't see any options for call forwarding in your settings, it's likely that you don't have an Enterprise Voice or Business Voice license. Also note that it can take up to 24 hours for changes in licenses to take effect.
If you have a license, please follow these steps to set up call forwarding:
To start forwarding your calls, select Settings and more ... next to your profile picture at the top of Teams. Then select Settings > Calls.
Under Call answering rules, choose Forward my calls, and then select where you want your forwarded calls to go: voicemail, another person, or a call group.
For more details, you could refer to: Call forwarding, call groups, and simultaneous ring in Teams.
