Is there a way to unlink mobile and desktop view

you can use Do not Display tool, for some specific sections or elements on specific breakpoints, so they will got different look, but the ULR would be the same

in general, if you would like to have different units of measure or colors on different breakpoints it is possible, but you need to remember about the cascading rule: https://support.wix.com/en/article/editor-x-designing-across-breakpoints-with-the-cascading-rule
