Create the mentioned CSS class not work in HTML web page without having access to HTML

Question

I have a website from e-commerce platform (Zid)

and I want to edit the mpbile view for Categories section from CSS

howverer, the view I want to make is just to remove the slider and make column photos

so I want to make the mentiond class of CSS in the HTML not working

but I don't have the accesablity to the HTML Structure

so how I can my mentiond CSS class not work?

you can see the capture here:

as shown it is a slider under the name (الأقســـام)

I want each photo on that slider to be in different row so it makes a vertical column like that

( Photo 1 in line 1
  Photo 2 in line 2
  Photo 3 in line 3 
  .. etc )

and all of that must be from the CSS as I don't have the accessibility to HTML file for the website.
