Visceral fat is literally enclosing the intestines, major blood vessels, organs, etc. of the abdomen.

Nevertheless, it is possible to surgically remove this sheet of fat that's covering your organs, it's called an omentectomy. But it's a big surgery, and done only in case of cancer, not for weight loss. That is, in humans: https://pubmed.ncbi.nlm.nih.gov/29367725/

Right. A surgeon can't just stick a liposuction tube into the abdominal cavity and poke around. This would be major invasive surgery with a high risk of complications, far worse than leaving the adipose tissue in place.
