Dear @mashyta2006
Not with any standard Lay Theme options sorry, but if you wish to go deeper this may help 🌝
I have a simple element (image) set with Parallax & within the HTML i can see a data value being set if the class has-parallax is present:

<div class="col no-offset push-3 span-11 align-middle has-parallax type-img no_100vh-carousel" data-type="img" data-yvel="2.7" style="transform: translate(0vw, -184.417px);"><div class="img " data-id="615">
There is this data-yvel="2.7 which relates to the speed set within the Gridder. Forcing a change to this value should change the the Parallax speed but i have not tested this personally.

Hope this helps & best wishes 🏖
