Add parallax background only to sections below portfolio

hi,

is it possible to get the parallax-effect in the background for lower sections on the portfolio page, but not the portfolio section itself? I would like to keep the blue in the portfolio-section, but have all the other sections below that with the background like the about-page (Über Uns).

code I used on the about-page :

<style>
.section-background, .page-section, .section-border {
    background: transparent !important;
}
body  {
    background-image: url(https://static1.squarespace.com/static/6543b43f555c594c9d98c11a/t/654a39a8043430171539d33b/1699363240540/BACKGROUND_WHITE_200.png);
    background-size: cover;
    background-repeat: no-repeat;
    background-position: center;
    background-attachment: fixed;
}

</style>

@CorinnaR yes try this: 

#collection-6548e6c4d402863b7021bc5c .page-section:not(.first-of-type) .section-background {
    background-image: url(https://static1.squarespace.com/static/6543b43f555c594c9d98c11a/t/654a39a8043430171539d33b/1699363240540/BACKGROUND_WHITE_200.png);
    background-size: cover;
    background-repeat: no-repeat;
    background-position: center;
    background-attachment: fixed;
}

@CorinnaR whoops, my code had a typo, that's probably why... it should be a colon before :first-of-type instead of .first-of-type - sorry! But good detective skills, glad it worked!
