Deleting selected notes from stories

This does the job:

var st = app.activeDocument.stories;
var c = 0;
var cSt = st.everyItem().notes.length;

for(i=0; i<st.length; i++) {
    for(j=0; j<st[i].notes.length; j++) {
        if(st[i].notes[j].texts[0].contents.indexOf("Info:") == 0) {
            st[i].notes[j].remove();
            c++;
        }
    }
}

alert(c + "/" + cSt + " notes removed.");

In this example, the note is only being removed if it starts with Info:.

Hello @Alex25077296wbvx ,

If you are already using a script for this, it seems to me that a supplement using "if" is enough to resolve the issue only in those that meet the condition defined in the "if".

It's worth noting that you can "look" and apply the "if" condition to what you want to delete or what you don't want to delete. It's just a choice of how to construct the condition, perhaps determined by how your content looks.
