you can simply set oomguarpages limit higher then vmprivvmpages. In this case postgres will get NULL on mmap() before OOM guarantee hit.

However, there is still one situation when OOM can happen - global memory shortage. In this case OOM selects any VE processes to kill. But this can not happen if you do not overcommit your node.
