The question has been answered here.
I paste:
You can use the anchors option to assign a different anchor to each section:
new fullpage('#fullpage', {
anchors: ['one', 'two', 'here', 'four'],
//your other options...
});
This way the #here anchor will be linked to the 3rd section.

The other option is just using the fullPage.js JS methods such as moveTo.
You can read more about anchors on the fullPage.js docs.
