Is it possible to apply light texture for EEVEE?

Is it possible to have something like this:

(from this tutorial: https://www.youtube.com/watch?v=bJ56n1CzRbI)

But for EEVEE instead of Cycles? I know EEVEE probably doesn’t support a dynamic light texture. But is there a way to “bake”(not sure if I use this term right) a lighting like this?

Put a light inside the canopy of a tree maybe. You need to increase shadow cube size as well playing with light’s radius and blend. Increasing the sample size also helps.

or with a plane with transparent mixed shader…

Why is it impossible using real texture inside the node? (with colors)?

Because the option to use Nodes for Lights is not available in EeVee…
You have to fake it…
In the above examples, you can add a color image, you just have to set the image color as the alpha, and the color to the Base color…but it will never work as well as it does in Cycles…
