Touchscreen gets disabled when I put the palm on screen

Actually I wanted to write some notes on my 'Android' tablet **Name: Lenovo Yoga Smart Tab** **Model: Lenovo YT-X705X** **Model no. - ZA540019IN** **Android version: 10** But I found that whenever I rest my palm in the screen, the screen becomes unresponsive. So, I did some touch testing and found that the screen isn't registering any touch when I keep the palm rested on the screen. So basically, when I keep the palm very lightly on the screen, it detects as one giant touch point, but if I keep the palm just like I keep on paper, then the entire screen becomes non-functional. Please tell me a solution. Is there some option in setting that is turned on or is it not possible to fix this?
