Where is syris gaming option?

I can’t find it anywhere.

Depends on where she is. If she's on Mhen'ga, it's automatic when you approach her after 12:00 (though if you're fuckbuddies with her, you can kiss her to go to regular interactions). If she's on the crew, it's the top-right-most button in her main menu (hotkey 5) and is only available from 12:00 to 20:00. If she's on Uveto, no gaming option exists.
