Is that down to the formatter - which you've configured to enforce a certain line length (https://prettier.io/docs/en/options.html#print-width) - or the diff visualiser that doesn't show a difference between whitespace and other changes?
It's impossible to turn off line length rules. You can only change the width, which means if you set it to a big number it will aggressively unwrap code you want to keep wrapped sensibly. Awful and unacceptable.
