SharePoint online - Disable "Select a template" welcome message and "Next steps" tips pane

Are there any solutions to globally disable the "Select a template" welcome message and "Next steps" tips pane for SharePoint sites? These appear when a user with Owner permissions visits the site for the first time.
In organisations where SharePoint governance is in place and site templating is used as part of a managed site creation process these are irrelevant and need to be disabled.
