Alphabetize checkbox_list field type

I have a custom post type, "Technical Documents", and have all these posts listed using a checkbox_list field type for the user to select which posts to display. However, there are 100+ posts and it would be easier to use if they were in alphabetical order. Is there a way to do this?

Thank you!

My code:

$meta_boxes[] = [
        'title'   => esc_html__( 'Technical PDFs to Display', 'online-generator' ),
        'id'      => 'selectpdf',
    'post_types' => ['product'],
        'context' => 'normal',
'fields'  => [
    [
        'type'       => 'post',
        'name'       => esc_html__( 'Select Product PDFs', 'online-generator' ),
        'desc'       => 'online-generator',
        'id'         => $prefix . 'product_pdfs',
        'post_type'  => 'technicaldocuments',
        'field_type' => 'checkbox_list'
    ],
],
];
