Is it possible to disable subsite creation in a modern team site?
You can turn this off for the entire tenant in the SP admin center. Settings>Subsite Creation.
Here's the text from the setting:
Control whether site owners can create a subsite in a site that includes an Office 365 group. This setting determines whether the option to create a subsite is available on the Site contents page when users click New.
That link is only visible to uses who have the create site pemission, which is included in the Full Control permission level by default. You can create a custom permisison level by copying the Full Control level and removing that specific permission. (changing the default Permission Levels is not a recommended practice)
see https://technet.microsoft.com/en-us/library/cc721640.aspx for the details.
The permission policies are not available anymore in Modern Team Sites. The options you have on the site settings page changed for Modern Team Sites. I would prefer an option within the Admin Center to control this option. Just like the option you have to show or hide the "Create site" option.
Any other options to prevent users from creating subsites and a way for limiting the Site Template selection?
Side note: i think it is really strange from a governance perpective that a "Joe User" that created a regular Group or Teamsite gets Site Collection administration permissions...
Many administrative pages are hidden for modern team sites, but they are accessible anyway using the direct URL.
For permissions, for example, you have to go to https://<tenant>.sharepoint.com/sites/<site>/_layouts/15/user.aspx
I am not interested in these administrative pages through hidden url's. Just plain and simple control over what users can do in a site. It seems strange that MS has a strategy of hiding stuff from users to keep it simple. Then it is rather strange to see that these users become Site Collection Owners and can created a Record Center below a simple team site...
Questions still stands:
1. Can we prevent users from creating subsites through a tenant level setting. For example the SharePoint Admin Center or PowerShell command
2. If the above functionality is not available, can we change the available site templates in the subsite creation dialog. Normally this can be configured for each site collection, preferably we want to configure this on the tenant level.
