Create module package

For Marketplace:

git clone https://git.example.com/Vendor_Module.git
cd Vendor_Module
zip -r9 "vendor-module-1.0.0.zip" . -x *.git* *.idea*

Alternative way (archive will have a path app/code/Vendor/Module/):

zip -r9 "vendor-module-1.0.0.zip" app/code/Vendor/Module/ -x *.git*

Disable event programmatically

use Magento\Framework\Event\Config\Data;

class Foo
{
    public function __construct(Data $eventConfigData) 
    {
        $this->eventConfigData = $eventConfigData;
    }

    protected function disableEventObservers(string $event): void
    {
        $observers = $this->eventConfigData->get($event, []);
        if ($observers) {
            $observers = array_combine(array_keys($observers), array_fill(0, count($observers), ['disabled' => true]));
            $this->eventConfigData->merge([$event => $observers]);
        }
    }
}

// usage: $this->disableEventObservers('sales_order_shipment_save_after');
