Here's one thing you can try.
If you are using Android Enterprise, you can deploy a Web App through the work Play Store:
1. Go to "Apps & Books" and add a new public app.
2. Select Android as the platform and click Next.
3. On the left hand side, select Web Apps.
There you should be able to add a new Web app pointing to the URL you require. There's also an option for the Web app to launch as "Full Screen".
The caveat to this is that Full Screen just works with HTTPS sites.
You can use this in conjunction with the VMware Launcher in order to get a Kiosk.
Another option would be to, instead of Chrome, use the Workspace ONE Web app which has the option to hide the address bar natively available and can be fully configured by Workspace ONE UEM (check your licensing to see if you are entitled to it).
Hope this helps.
