Sure – give this a try in your Customizer‘s CSS panel:
/* Move projects above blog on the front page */
.home .site-main {
display: flex;
flex-direction: column;
}
.home .portfolio {
order: 1;
}
.home .journal {
order: 2;
}
.home .about {
order: 3;
}
.home .social {
order: 4;
}
Let me know how it goes.
Also just a heads-up that since your site has a Premium plan, you’re entitled to live-chat and email support, accessible here:

You’re welcome to still post in these forums, but those other support avenues may be faster, and you’ll always get a staff reply.
