You need to use a Canadian address for shipping, and use a shipping forwarding service like Reship which will provide you with a unique suite number at the address of their Canadian forwarding facility. Upon receipt, Reship in Canada then ships the package to you in the U.S. at your address.
Not yet sure about tariffs and customs from Canada to the U.S., but the delivered Canadian price for the Creator Combo is just under $4,000 U.S. dollars, with the actual merchandise price at $3500 U.S. dollars upon which any tariffs would be computed. B&H price, delivered, if they ever get any, is $5,000 to CA, leaving plenty of room for tariffs (up to 43%) on top of the $4,000, should they need to be paid. Warranty would be through DJI Canada.
