Yes, it's possible to display it as 2 columns using CSS to break up the page. Example as follows uses flex to make the fields of a tab on the registration form into a 2 column grid.
Code:
.cbRegistration .cbFieldsContentsTab {
display: flex;
flex-wrap: wrap;
}
.cbRegistration .cbFieldsContentsTab > .cb_form_line {
flex: 0 1 50%;
}
