How to disable system scaling in a Qt application?

Question

Qt

Hello! In the Qt designer I draw a form, I work on two PCs. On one, the usual system scale, and on the laptop, in view of the small screen, the system scale is set to 150% of which the form looks different and moves apart. Tell me how you can control this scale and turn it off for an element or the entire application?

QApplication::setAttribute(Qt::AA_Use96Dpi);
