Conditional enqueue script (JavaScript)

I have 3 plugins all of which require Google Maps API to load up (separate keys are used on each plugin too).

However these are loading on each page causing errors.

Now, I have decided to conditionally enqueue each script like so;

add_action('wp_enqueue_scripts', 'add_script_function');
function add_script_function() {
    if (is_page(2393)) {
        wp_enqueue_script('SERVICESGMAPI', 'https://maps.googleapis.com/maps/api/js?key=KEYHIDDEN&libraries=places&language=en-GB');
        );
    }
}
add_action('wp_enqueue_scripts', 'add_script_function');
function add_script_function() {
    if (is_page(vacancies)) {
        wp_enqueue_script('VACANCIESGMAPI', 'https://maps.googleapis.com/maps/api/js?key=KEYHIDDEN&libraries=places&language=en-GB');
        );
    }
}
add_action('wp_enqueue_scripts', 'add_script_function');
function add_script_function() {
    if (is_page(events)) {
        wp_enqueue_script('EVENTSGMAPI', 'https://maps.googleapis.com/maps/api/js?key=KEYHIDDEN&libraries=places&language=en-GB');
        );
    }
}

BUT, with the events page, each event is permalinked like so;

• mydomain.tld/event/marathon
• mydomain.tld/event/meeting
• mydomain.tld/event/EVENTNAME

So the code above (3rd part) will load the script on mydomain.tld/events, how can I set it to work on the event/* pages?

Also, the scripts are being loaded via the plugins, if I change that via editting the plugins, changes will revert on updates. Any advice?
