You can consider multiple background like below:

body {
  margin:0;
  height:100vh;
  background:
    linear-gradient(to top left, transparent 49.8%,rgba(0,0,0,0.3) 50%),
    linear-gradient(to top right,transparent 49.8%,rgba(0,0,0,0.3) 50%),
    url(https://picsum.photos/1000/800?image=1069);
  background-size:
    50% 100%,
    50% 100%,
    cover;
}
