My enterprise license is public, can something be done about it?... NOT REALLY

Unfortunately, there is nothing to prevent this.

From our docs

https://www.ag-grid.com/javascript-grid-set-license/

If you are distributing your product and including ag-Grid Enterprise, we realize that your license key will be visible to others. We appreciate that this is happening and just ask that you don't advertise it. Given our product is JavaScript, there is little we can do to prevent this.

Is important to note that ag-grid-enterprise is made available as an open source project, which means that if anyone wants to pirate a license they can just use the freely available version without a license.
