Can MDM enforce app link / default URL handler registration?

We have a BYOD deployment where users enroll their personal Android devices and get a work profile. Inside the work profile, we deploy an internal app that handles URLs for one specific corporate domain (e.g. internalapp.company.com). We also deploy Edge as the default browser in the work profile.

Desired behavior:

• Links to internalapp.company.com → open in our app
• All other links → open in Edge as normal

The problem: We cannot host assetlinks.json publicly on that domain, so standard App Links verification is not an option.

What does work (manually): On each device, going to Settings → Apps → [Our App] → Open by default → Add link and checking the domain works perfectly. After that, links from Slack, email, etc. open in our app as expected.

But we have hundreds of devices and need this enforced administratively through MDM (Intune/WorkspaceOne).

Has anyone found a way to push this domain-to-app association via MDM policy in Work Profile mode? Or any other enterprise-managed approach that avoids the assetlinks.json requirement?

Appreciate any ideas, this feels like it should be a solved problem for enterprise apps on internal domains, but we're hitting a wall.

Thanks!
