Hi there. ??
There is absolutely a way to get your projects to display in a random order but it will take a few steps and some comfort with HTML/basic PHP.
As a starting point, you should set up a child theme. The following guides give good introductions to child themes, including steps to set them up:

After you have set your child theme up, copy the page-templates/portfolio-page.php file from the parent theme to your child’s directory.
Next, open up the new file in your child theme’s directory in your favourite text or code editor.
$args = array(
'post_type' => 'jetpack-portfolio',
'paged' => $paged,
'posts_per_page' => $posts_per_page,
);
To order your portfolio items in a random order, we need to add the following to this list of arguments:
'orderby' => rand,
The updated snippet of code will look as follows in your child theme:
$args = array(
'post_type' => 'jetpack-portfolio',
'paged' => $paged,
'posts_per_page' => $posts_per_page,
'orderby' => rand,
);
In case you’d like some more explanation about what we’re editing here: The arguments are passed to a class called WP_Query, which you can read more about on this Codex page:

Let me know how you get on with that or if any extra questions come up.
