You should be able to do this as follows:  

1. Right-click on any column heading on your Related list and Configure=>List control=>Omit New button

2. Check Omit New checkbox

2. Write your script in the Omit New condition Script field (if not on your form configure the form to show it) 

If you have never done this before this video is a decent walkthrough of the process: https://www.servicenow.com/community/developer-blog/how-to-hide-new-button-from-related-lists-using-...

Hi,

Try this in Omit New Button

Right click on the list header -> Configure -> list Control

var answer;
 if(current.getRowCount() > 0) {
    answer = true;
}
else {
  answer = false;
}
