I've got my phone since jan 2022 (still at miui 12.0.3) never got a ghost touch. But a week ago i activated schedule dark mode and always ghost touch every night and morning, specially when device got hot (playing something while charging).
Since 2 days ago i deactivate the darkmode schedule, and haven't got ghost touch yet. maybe this would work on your phone too
*sorry for my bad english
