For amdgpu I’m using

Section "Device"
     Identifier "AMD" 
     Driver "amdgpu"
     Option "TearFree" "true"
EndSection

For nouveau driver I didn’t find similar solution.

Option "TearFree" is an amdgpu-specific X11 driver option. No such provision for the the xf86-video-nouveau driver.

If you’re using X11, the usual approach is to let your desktop compositor (eg KWin, GNOME’s Mutter, Xfwm, etc) handle vsync (ie vsync enabled). If you’re using Wayland, the compositor is responsible for presenting frames to the display in a synchronized manner, so screen tearing is generally not an issue.
