G-Sync it self is already enough. it will sync the frame from gpu to monitor with less latency compared to vsync,
As per my experience, when i borrowed my friend's 165hz monitor, a g-sync compatible monitor (freesync monitor), the screen tearing only appears if the FPS dropped below 120fps, in the means "Really Feel" it. So GSync on + frame limiter is already more than enough. but try to use only gsync.
If you care about fps then try to adapt with the tearing, eventho i hope for a noticable screen tearing, i tested 1 match of valorant without any syncs both monitor and NVCP etc etc, i didn't see any screen tearing at a really visible level, frame capped and un capped, both are almost identical.
I usually dont do any syncs cause...
