@sharptools501, you can use the REST API syntax described in the post below in the Hyperlink tile to send the GET request to your PiCore server without opening the link.
For example: (please note that the URL is wrapped within the double quote", not the “ and ” that the community s/w decides to display.)
–EDIT–
This wouldn’t work in this specific scenario because it REST API syntax requires HTTPS since most browsers will throw mixed-content warning if sending request to an insecure endpoint.
