Selective deactivation of GP typography settings

Hi,

Hope you are well.

I’d like to deactivate the Typography > Headings > Font size / Line height / Margin settings. Unfortunately, they are in conflict with custom CSS settings for fluid/responsive typography.

  .body {
  font-size: calc(16px + .21vw);
  line-height: calc(21px + 1.4vw);
}
  .body H1 {
  font-size: calc(21px + 1.89vw);
  line-height: calc(21px + 4.2vw);
}	
  .body H2 {
  font-size: calc(21px + 1.19vw);
  line-height: calc(21px + 3.15vw);
}
  .body H3 {
  font-size: calc(21px + .49vw);
  line-height: calc(21px + 2.1vw);
}

Could you help me with that, please?
