Default Owl Carousel

The Aedificator theme uses the owl Carousel by default, for the homepage sliding gallery.

I need to try and apply a fixed max height to this, to bring the below content further above the fold, but cannot seem to find any support or solutions for this.

I am also hoping to be able to add more than x2 images to the slider as the fields in WordPress only allow for x2 to be selected and added.
