Dear Kiutzy,
By default, its pre-built in the slider so it can’t be removed.
So, we suggest you update the images for the slider in the feature slider section.
You can follow the path below:
Appearance ->Enable Feature Section ( Check the box)
Appearance->Customize->Featured Section Options->Feature Slider Selection
Choose Page/Page Repeater from the drop-down menu of Slider Selection From
Choose pages from Select Slide of Slider in Slider Selection and publish the page.
Best Regards!
