It depends on where the tear is, but it's certainly possible. The microphone is on [link|https://www.mobilesentrix.com/power-button-flex-cable-for-iphone-11-pro-max|its own "branch" of the cable|new_window=true]. So if only the mic part was torn, it may not interrupt any other functions. Some pictures of the damage might help,
But I suspect you're on the right track. Yes to the correct cable, and yes an OEM pull or a "premium" cable.
