How to safely prevent Teams from going into Away mode?

Hi guys, I would like a secure way (ie that the monitoring doesn't catch, if any) that teams is always online. I want to read books or study without Teams bothering me saying I'm away when I'm at the table. It's really bad to have to keep moving the mouse every 5 minutes, it takes away the total focus. Is leaving a weight on a key untraceable? I want to take advantage of downtime in a better way than staying on my cell phone. thanks
