Both those switches were removed between iPhone 12 and 13 models. Which is sad, because they’d go a long way to avoid the issues described in the article.
It seems that not all iPhones do have this setting available. Not sure if this is related with the availability of RAW images, which is only supported on iPhone 14 Pro.
I may have missed something and had the impression that this was a "new" feature for iPhone 14 Pro only. But as the linked support documents mention, it is available on iPhone 12 Pro and later Pro models since iOS 14.3.
