Hello,
Sorry, but the desired result is unclear for me. Please provide ULR of demo page as example.
Theme Options > WooCommerce > Shop > Shop page layout > disable sidebar.
To make Brands widget visible, you need to create brands https://prnt.sc/OZ1CMEC-9J_H and associate them with products.
Disable “Use ajax preload for this widget” in Shop Filters area, clear cache and check Shop page https://prnt.sc/USTy1YM1-KhQ https://prnt.sc/iMsCcLfFlr01
