Tesla has strong logistics. They compare standing orders to inventory on the ground and expected to be coming off the line. If you are lucky, they will find an inventory configuration acceptable to you, and notify you that one is available. If there is no physical vehicle available, and the plant is closed down, then you will need to wait til the factory reopens. Alternative is to contact your delivery specialist and see what might be available right now. Might not have your exact desired configuration, but might be good enough.
Different seats, wheels, color etc might still be acceptable to you, if getting it delivered right now is an incentive.
On the negative side, some regional locations are under embargo. Deliveries for those areas will most likely be shunted to areas open for business. Also, if you car does not pass final inspection, then that vehicle also will no longer be fit for delivery and postponed.
