How to get rid of welcome screens for the guest user in Windows 11 for Education?

Simple thing really: I successfully created a Windows 11 Education setup with “Shared PC” settings, i.e. there’s a guest user who can logon anonymously and whose changes will be reverted after every logout. This means, however, that every application under the sun (and Windows itself) thinks that the user has to be presented with their various welcome screens.

Windows shows me the “Touch gesture tips!” screen directly after logon
Office presents the “Read this and then press Accept for data privacy stuff” screen
Edge / Firefox / … show me their: “Hey, you’re new here! Click through these 10 screens first!” stuff
And so on.

I’ve been unable to find anything to fix this because as soon as I combine the words “disable” and “guest account” in any kind of way, every search engine thinks that I want to disable the guest account.

So, what do I need to do to make those welcome screens go away?
