If you want your tab to switch instantly, the new tab should render fast. If it can't render fast, make the rendering lazy. You can use something like that: https://gist.github.com/slorber/d473b9217b54427f3dec128bf08e14a2

I’ve been using React Navigation for a long time and only time I’ve had any noticeable delay it was because of to my tab component was slow to render, not changing the tab per se.
