Yes you can.
You can use this css:
.mslider .mslider-item {
top: 0;
transform: none;
}
This will align items top for all sliders.
If you want to change only the current slider, enter a suffix at
widget > settings > layout > class suffix
and then use:
.YOUR_SUFFIX .mslider-item {
top: 0;
transform: none;
}
