Teams Apps (MS apps) use First Name instead of Display Name

Some apps in Teams use an accounts First Name value instead of their Display Name value. We've also found that Microsoft Forms does this, too (but that's for another discussion). For example, the Games for Work app in Teams is a Microsoft Corp app and it uses the First Name value. 

Here is the issue a user brought to us:

What if this is a member of the LGBTQ2+ community and using the First Name value makes them feel "outed"? Is there a way for us to force the apps (the Microsoft apps in particular) to use Display Name (as this is what we want everyone to see) instead of First Name?

I know the first solution is to change it in AD, but we can't do that because our First Name and Last Name values in AD are synced from Oracle (HR system) where we must use birth / legal name. I have let the user know that in order to change First/Last Name values, they'd have to provide legal paperwork to HR about an actual name change.

But does Microsoft have a way of forcing/requesting/defaulting Teams apps to use Display Name instead of First Name?

For example, say we have a user whose Display Name is Taylor Smith and their First Name value is Timothy, Last Name value is Smith. In the Games for Work app, it uses Timothy (First Name).
