acer swift 1 SF114-31 touchpad not working even after driver reinstallation

Hi, have an acer swift 1 (SF114-31)
Fresh win 10 install - touchpad won't work. Installed ALL drivers off acer website, ran all windows updates. Still no luck, scroll or click. - not even detected by device manager. External mouse fine. Please someone a solution please. And yes have tried FN F7 before someone mention.

Thanks.
