Hi, thanks for reaching out.
I took a quick look around but don’t see a related setting. Unfortunately, this isn’t a task I’ve tackled in the past. You could perhaps open a support topic on the Meta Slider forum, hopefully, they’ll be able to lend a hand https://wordpress.org/support/plugin/ml-slider/.
Alternatively, you could take a look at what Smart Slider has to offer https://smartslider3.com/blog/animations-effects-smart-slider-3/.
