@TestUser, Thanks for posting in Q&A.
From your description, I know you want to stop user from accessing google app.
Based on my research, there is no such feature in Intune that can achieve your goal, but if you do not want user to use google app, we can uninstall it to stop using it.
Please note if you deploy google app via Intune, you should configure it as Uninstall under Assignment page or it will auto install on your device when you uninstall it manually.

Non-official, just for reference.
Hope it will help.
