Hi Mitch
Good to hear from you again.
I had a look at Chrome settings in Android Enterprise policy, there is a possibility to fill in field and value for this using the page below.
https://chromeenterprise.google/policies/#HomepageLocation
You would use field "HomepageLocation" and value "URLtoopen" where URLtooopen is the address you want to launch.
Please note just FYI that there is also a possibility to configure Samsung Browser for handling cookies etc.
Hope this helps!
