schema remove link

Hi

I have link which listed on the schema list that I wanna get rid of,
sample code that I wanna get rid of:
{
“@type”:”ListItem”,
“position”:”2″,
“item”:{
“@id”:”mysite.com”,
“name”:”Homepage”
}
is there any code that i can use like
if ( id=”mysite.com” && name=”Homepage”) then remove
I tried the breadcrumbs homepage setting on rank math, either I use that or not the link wont go away.
Thanks
