Hello,

If I follow you properly, you want to hide this block https://gyazo.com/0681a75907e6048488dd8adac4b57293

You can hide this section in the section settings as shown on the screen.

You can hide section or columns this way.

I see you have set Mobile version HTML block (experimental) https://gyazo.com/d94ba8ff9b071a41482dedc6e94affda

I am checking the HTML block you have set. You have hidden the sections on the desktop and mobile, please enter each section and make it visible. In this case, in mobile, your home page would be replaced with this HTML block. You do not need to hide the sections as the whole HTML block would only appear on the mobile. https://gyazo.com/6fa499c6bfdc9eddfc1be5324a2d0bc5

If you want to remove the HTML block in the Mobile version HTML block (experimental) you need just deselect the block: https://gyazo.com/a5804f35949ad0c021bd3816e2a5faf5

Best Regards
