Yes! I have been searching the web too and just found code to do this. First you need parallax enabled in the Site Design. This code will disable it on any standalone or index page you specify.
You first need to look up the data-parallax-id that is specific to the background image. Then just replace it in the code below, and add to your custom CSS.
[data-parallax-id="PLACE ID HERE"] figure {
transform: none !important;
top: 0 !important;
bottom: 0 !important;
will-change: auto !important;
}
