Four Euro 2020 places are also up for grabs via play-offs in 2020.
England face Spain on Saturday in the opening round of fixtures, live on Sky Sports, while Northern Ireland host Bosnia and Herzegovina.
Scotland play Belgium in an international friendly on Friday before they open their Nations League campaign at home to Albania on September 10.
Meanwhile, Wales and the Republic of Ireland meet at the Cardiff City Stadium on Thursday.
