Default sharing settings on new sites?

[Daedalos]

Does anyone know if there is a way to modify default settings for creating new site? I am mainly interested in modifying default sharing options so that only owners can share. We have a customer where multiple people create sites, and they often leave sharing settings unchanged, and we would like to limit sharing to owners only as default.

@Daedalos Several ways to do this:

Use Azure Automation and a scheduled PowerShell task to disable members from sharing

Set-SPOSite -Identity https://contoso.sharepoint.com -DisableSharingForNonOwners

 Create a Site Design to automate the setting or even multiple settings post creation:

Hope that helps.
