Annoying multitouch behavior Elantech touchpad on Linux Mint 20.2 Cinnamon

Recently I installed Linux Mint 20.2 Cinnamon. Touchpad multi finger behavior is strange and annoying. When I tap with two fingers exactly at the same time, it performs right click and if one of my fingers touch a little later than the other one, it performs middle click. Three finger tap doesn't work. Changing **Click Actions** in **Mouse and Touchpad** seems to have no effect. Currently I disabled **Tap to click** to prevent accidentally paste, closing tabs, opening links, etc. while performing *Two-finger scrolling* or tapping. Here is output for $ xinput --list-props X command:

$ xinput --list-props 13

I tried to edit *libinput Tapping Button Mapping Enabled (307)* by $ xinput --set-prop 13 307 X Y. Changing it to 0 1 didn't have any effect. Other values return error. In Windows touchpad behaves OK for two and three finger actions. I think Ubuntu and previous versions of Linux Mint were OK too. External mouse works well. How should I set three fingers for middle click and two fingers **just** for right click? (or at least disable middle click for two fingers)
