You can simulate this using CSS variable that you set instead of start and use it to reset the counter. For semantic purpose you can also keep start attribute.

.custom {
  margin: 0;
  padding: 0;
  list-style-type: none;
  counter-reset: step-counter calc(var(--start) - 1);
}

.custom li {
  counter-increment: step-counter;
  margin-bottom: 10px;
}

.custom li::before {
  content: counter(step-counter);
  margin-right: 5px;
  font-size: 80%;
  background-color: rgb(0, 200, 200);
  color: white;
  font-weight: bold;
  padding: 3px 8px;
  border-radius: 3px;
}
