Team boss Claire Williams will not attend any more races in 2017.
The 41-year-old, who is the daughter of team founder Sir Frank Williams, is due to give birth to her first child - a baby boy - in the coming days.
Claire said at Monza that she will be working from home from now on this season.
"It's a bit strange because I've been here for so many years and I'm going to miss the last races of the year," she said.
"I'm a little sad because [the paddock] is my home, it's my office."
Williams are currently fifth in the team standings.
