Hide specific value from dropdown on form - help center using javascript

Hi All,

Is it possible to hide the a specfic value from the dropdown list on the form (help center) using javascript.

Currently I tried and even though the value is not showing up element (developer console), but I can still see the value on front end form.

this is my current code:

if(HelpCenter.user.role == 'anonymous' || HelpCenter.user.role =='end-user' || HelpCenter.user.role =='manager')
    {
      $('#request_issue_type_select option[value="13504813503517"]').remove(); 
    }
