Help please diminish unison

High everyone, please remind me how to set up, the engraving options, so that i, don’t get that line. I am looking everywhere but I don’t remember how this style is called that’s why probably I can’t find it.

Notation Options > Accidentals > Altered unisons

Select Single stem.

Hi Craig! Thanks a million… I was looking in the wrong place, Engraving options, that is why I couldn’t find it.

All the best,

Carlos
