B extending standard fence.
You can use post extensions.
While a solid privacy fence might be 6 feet height adding an additional two foot extension will give you an added visual component since those last two feet will be made of lattice or open work to reduce wind resistance.
There was a fairly low 4 foot fence between houses.
If you have a wire fence maybe a neighbor can wire this addition on and make a longer post to make it stronger then add a bush like a rose of sharon and this w ill grow and create your privacy that you desire.
Even if your fence isn t vinyl you can use these methods to connect lattice to your fence.
To raise the height the posts were extended and new boards were added at alternating lengths.
Once you have the post extended to the desired height you can use rails or build a frame to add the lattice between posts.
If you want to gain height to your current vinyl fence you ll need to extend the post as well.
It s arguably the best choice for privacy.
You didn t tell us what type of fence you do have now.
