How to disable some certain blocks on mobile/tablet view?

We are suggesting you 2 solution

1 - When you create a block by builder, you can add custom class to Custom Class field on builder, so if you want to hide it on mobile, let add this class: hidden-xs hidden-sm

2- You can use custom style, please use this syntax

@media(max-width: 1199px){

.call-out-the-specific-classes{

display: none;

}}
