Hello everyone, this is my first post!
I want to make a animation which make a spline visible from point A to point B. Can Synfig do that?

You can use the Width handles on an Advanced Outline to animate a line drawing along the path.
It looks like you already have an advanced outline, so all you would need to do is toggle the width handle visibility ( ) and start tweening.

Here’s an example
