Is it possible to disable subsite creation in a modern team site?
Is there a way to prevent users from creating subsites in a (Group) Modern Team Site?
If not, is it possible to control the templates made available?
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.

- Bad news about this solution - in fact this only hides the 'create subsite' button in the Modern site contents page. If the user selects the 'Return to classic SharePoint' option in the bottom of the left column of the Site Contents page, site owners still have access to the 'Create sub-site' option.
Hiding the button will stop most users but the more technically savvy users can easily discover how to get around this after doing a quick online search. I have used this tenant setting to turn it off ("Hide the Create site command") but it does nothing. Site Owners with Full Control are still presented with the 'new subsite' command, and are able to create one. Even on newly provisioned site collections (created after I configured this setting). Maybe I'm missing something, but it seemingly takes no effect throughout my tenant.
It seems that settings in the classic Admin site don't impact modern sites very often. In the new admin center you can disable the overall creation of sites but it doesn't have a subsite creation feature (YET). I would expect to see it there because you can also see Groups in this admin center while you can't do that in the classic. It's really a transition phase from Classic SP Admin center to the New Admin center.
Thanks for this. Any idea when this functionality was added to the Admin Center? I don't recall seeing any announcement about this.
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
