Thanks for the question, HeyHey16K. We are in the process of updating our docs to state that multi-app kiosk is indeed supported on Windows 11 and can be configured via Intune. This is something that can be configured using a kiosk configuration script and OMA-URI settings in Intune. See Peter's blog on how to configure this: Configuring multi-app kiosk mode on Windows 11 – All about Microsoft Intune (petervanderwoude.nl)
