Thanks @southernb for pointing me to the solution. This did the trick!!
Add to functions.php:
function deregister_tribe_select2() {
$current_screen = get_current_screen();
if( $current_screen->id !== "tribe_events" && $current_screen->id !== "tribe_venue" && $current_screen->id !== "tribe_organizer") {
wp_deregister_script('tribe-select2');
}
}
add_action('admin_enqueue_scripts', 'deregister_tribe_select2');
