so find others posts: enable igpu to primary
but i cant set the hd530 pre-os share memory ,because bios no that option.i already flash the bios with hp support.

Use the minStolenSize patch if you can't set DVMT-prealloc to the required value.
See [README] Common (some unsolved) Problems in 10.12 Sierra
