Sure. If the slider has been assigned using the Page Slider meta box in the right column you can set full-width stretch there.
If the slider is in the page body then you can insert it using a Meta Slider widget and set the row to full-width stretched by editing the row, clicking Layout in the right column and then Full-Width Stretched. If you’re inserting a slider into Page Builder you have to stretch it by editing the slider in Meta Slider, clicking Advanced in the right column and then enabling the 100% width option.
