Defer Javascript Element Conflict

I have a custom calculator I made with jQuery that has worked great until Siteground added "Defer Render Blocking JS" as a setting to their SG Optimizer Plugin.

The jQuery I coded is inserted into one post using the elements feature in Generate Press. It currently goes in the 'wp_footer' hook.

When I have the render blocking setting turned off in the SG Optimizer Plugin it works fine, and does not work at all when I turn it on. When turned on it gives a console error that it doesn't recognize 'jQuery' function, so I am assuming it is not loading jQuery before the element's code.

Is there a way I can get these two things to play together? I would like to have it turned on but open to other ideas.
