@Paulie555 If you're talking about the Mac Dock creating Dock item for those and having a Policy with a  Dock Items payload set to remove those works for me. Here's the Paths I use for this Dock items:

file:///Applications/FaceTime.app/

file:///Applications/TV.app/

file:///Applications/App Store.app/

@sdagley This isn't working for me (same path as yours) 
Have tried this on multiple macs

This applications are in the System Folder, try with the below path 

file:///System/Applications/FaceTime.app/

file:///System/Applications/TV.app/

file:///System/Applications/App Store.app/

may dockutil helps?

We are using this script with dockuitl

We use @kcrawford dockutil for managing dock items.

Thanks

@Paulie555 Any chance your policy isn't running when a user is logged in? I haven't tested to be sure but I believe the Dock payload is only applied to the logged in user.

We've also used dockutil and it has worked for us. However, ever since upgrading some of our computers to Sonoma a year ago, dockutil hasn't really been working. I haven't spent much time looking into it since it's been a low priority for us, but I am curious as to whether anyone who uses dockutil has noticed any issues on computers running Sonoma or Sequoia

@BookMac does Dockutil work on newer machines/ latest OS?
Obviously don't want to end up with outdated systems

@Shyamsundar  have tried this path with no success either 

@sdagley User is logged in when the policy runs so not sure why my results vary from others

yes. works on sequoia with M4

Hey all,
Managed to work out the issue with the in house Dock policy
Path names were correct, however the display names for each app were not exact

Thanks all for the help and advice

I know the original poster already resolved their issue, but I just wanted to mention that dockutil seems to be working just fine now on computers running Sequoia (and I haven't made any changes or did a testing since the last time I made my post here). As long as it works, I'm not complaining!

Looks like the names of the dock items are case-sensitive and have to be exactly right:
FaceTime -  file:///System/Applications/FaceTime.app/ 

file:///Applications/App%20Store.app/

file:///System/Applications/App%20Store.app/

Might help.
