i think it is possible when you “adapt” this dynamically-populate-a-select-fields-choices and combine it with your function to scan the directories.

for first dropdown do something like that:

function acf_load_color_field_choices( $field ) {
    // reset choices
    $field['choices'] = array();
//fill here your array into the variable $choices
$choices = php glob() function that you have;
//
    // loop through array and add to field 'choices'
    if( is_array($choices) ) {
        foreach( $choices as $choice ) {
            $field['choices'][ $choice ] = $choice;
        }
    }
    // return the field
    return $field;
}
add_filter('acf/load_field/name=color', 'acf_load_color_field_choices');

for second dropdown, you need to get the value of first dropdown and do nearly same again.
hope i have understand you right, and this answer help. or at least lead you to the right direction
