Respectfully, no it's not.

Screen *tearing* is when your FPS surpasses your refresh rate causing parts of more than one frame to be displayed during one refresh cycle; vsync is essentially a frame cap which kicks in once the refresh rate is reached to prevent this.

VRR/Freesync/Gsync is for when your FPS drops *below* the screens refresh rate (microstutter/blur) and tells your monitor to adjust the refresh rate accordingly (up or down within the refresh rate range) in real-time.

Edit: To clarify, I'm not advocating vsync on, in general it should be off unless you're particularly sensitive to tearing, just that VRR does not prevent screen tearing.

Edit 2: If you disagree, it's simple to verify. Turn on your available VRR without a frame cap or vsync on. Load up a game where the FPS will exceed your refresh. Look at the evident tearing. Turn on vsync or a frame cap (2-3fps below your refresh rate), watch the tearing disappear.

This is wrong. You can get screen tearing with frame rates below your refresh rate and Vsync works at any frame rate. Tearing is simply caused by the refresh rate of the monitor being out of sync with GPU frame rendering and buffer swaps. This can happen at any frame rate. Standard double buffered Vsync simply forces the GPU to wait until the monitor has finished a refresh before flipping the buffers and rendering the next frame. 

Adapative sync technologies like FreeSync and Gsync can entirely or mostly eliminate tearing on their own, but it's not perfect. That's why it's recommended to use Vsync in conjunction with these technologies, in addition to a frame cap to keep your frame rate within the adaptive sync range. The Vsync works in conjunction with adaptive sync to compensate for frame time variances and completely eliminate tearing both in and out of the adaptive sync range.
