Hi @m123,
Please go ahead to Custom codes > custom JS (Body), and paste this custom JS code:
<script>
// index of products to be hidden (1 is the first).
let productsIndices = [1,3];
productsIndices.forEach(p => {
document.querySelectorAll('.pl-items .pl-item')[p-1].style.display = 'none';
})
</script>
Ps: [1,3] are the indices of the products the script is going to hide, feel free to edit them however you see fit.
