BYD SEAL U DMI REPAIR after airbags opened

Does anybody know if BYD is repairable after accident with airbags open? My BYD SEAL U DMI after airbags opened does not go into OK state and only possible to go into N or P gear. Airbag system is fixed at workshop... Or its only way to change HV battery for new one as dealer tells? Does it lock itself or have some fuse? I can't find any information on web... It's like biggest secret of modern age I someone can share some experience or URL to information - that would be very helpful. Thanks!
