How to change default slider layout on homepage?

Hello all,

I would like to change the layout of the AccessPress Mag theme in such a way that I have 3 thumbnails one next to another horizontally, or, if there are only two thumbnails available, to switch the homepage slider to two slides one next to another?

Here is the example of what I’d like to achieve: https://imgur.com/mmHoiS2

Thanks guys, great theme overall!
