If you require hosting to have SecFilterEngine Off or SecFilterScanPOST Off, do not worry.
Those rules apply to Apache 1.x, but HDWEBPROVIDER™ uses Apache 2.x.
We can't completely disable mod_sec, but we can find the rules blocking your scripts (403 error) and disable those rules. Thus, we can meet these requirements.
Simply contact HDWEBPROVIDER™ via phone or live chat to report mod security blockage.
