found a CSS work around
/* STRUCTURE */
.wrap {
max-width: 80% !important;
}
.page.page-one-column:not(.twentyseventeen-front-page) #primary {
max-width: 100% !important;
}
@media screen and (min-width: 48em) {
.wrap {
max-width: 80% !important;
}
}
@media screen and (min-width: 30em) {
.page-one-column .panel-content .wrap {
max-width: 80% !important;
}
}
@media screen and (max-width: 650px) {
.wrap {
max-width: 95% !important;
}
}
