Oculus Browser - set start page?

I have a fleet of headsets through Oculus for Business. We deploy Oculus Browser on it for our WebXR project.

Is it possible to change the start page in the browser, so that our site comes up automatically? If so, is it possible to do through Workplace?

Currently, we set a bookmark to the site when we provision the headsets, but this has to be done manually on each headset, and the users have to remember to look in the bookmark list.
