Hi,
Based on your update, it appears your SteelSeries headset is connected using a wired connection rather than Bluetooth. In that case, the Hands-Free Telephony setting and the Services tab shown in many guides may not be available because those options are typically associated with Bluetooth devices that support the Hands-Free Profile (HFP).
Since disabling Hands-Free Telephony is not applicable to a wired headset, the next step is to focus on the specific issue you're experiencing (for example: poor audio quality, microphone not detected, microphone quality issues, or audio playback problems).
Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
