Hi,
I haven't known much about Skype for Business registry keys since there's only a preview version.
Anyway, I learned something from the previous version(Lync) to disable the Welcome screen, I tested it and didn't get the tips, please try if this works for you:
Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.
Press Win + R, type "regedit" in the blank box, press Enter.
Browse to:
HKCU\Software\Microsoft\Communicator
Create the DWORD: FirstRunPlayed
Set the value to as: 0
We can create this value on a test machine and check if this works. If yes, deploy it to all users then.
Regards,

I can confirm that the IsBasicTutortialSeenByUser registry value is correct and is detailed in the following article: https://support.office.com/en-us/article/Switching-between-the-Skype-for-Business-and-the-Lync-client-user-interfaces-a2394a4c-7522-484c-a047-7b3289742be0?omkt=en-us&ui=en-US&rs=en-US&ad=US
Scroll down to the section 'Control the display of the Welcome screen tutorial'.
