You can do this by updating the hidden property in the feature.xml, but I recommend against changing any of these files in the layouts/features. You could also do this using PowerShell and update the feature through the object model.

But there is one big issue to setting the features to hidden. Some of them have dependencies on others. SharePoint does not allow hidden features to have dependencies. Actually, you can set a feature to hidden that has dependencies, but SharePoint will never allow you to activate it and will throw an error.

So it will be tough to hide the features from site collection admins. But you might be able to hide permission for site owners (non collection admins) by giving them a custom permission level below full control. I think the one to remove is Manage Web Site. Or you could remove other levels as well to restrict an owner.

Also note, if you change the feature.xml and then update Nintex with a new build, your changes will be lost most likely.

Hello,

Finally I decided to write my own solution which can be manually started after each Nintex update or scheduled via windows task scheduler:

This is great information to share and useful to the community! I just want to note that for those that want this ability to hide the features there are a few things to note. You will not copy and paste this PowerShell into an editor and just run it. He created two pieces, one to remove the dependencies of the features and hide the feature, the second to activate the features on a site (because now they are hidden). You will not run the hide script more than once, like once per site.

Any updates to Nintex that are installed may overwrite the feature xml files that this script is changing and thus make the features visible again.

Make sure your path to your 15 hive is the same as provided.

And Csaba Sztancsik‌, I want to thank you for this, and it is very useful, but it would only be fair to mention to those that want to use it that changing the Feature XML file of a feature isn't the best of practices and could affect your farm. Test it out before you use it in production. But if you have to hide the features from your site admins and you cannot simply change their permissions, this is really the only way to do it.

We are facing the same error in SharePoint 2016 while saving site as a template.

I can see in the logs that a feature.xml has been changed and SharePoint is not able to detect this as a result of which it says feature with dependency not found.

I can see the PowerShell above to show changed features.But the csv has listed the Nintex 2013 features in it.

Can you please provice me a list of Nintex 2016 features so that i can run the PowerShell and detect which features have been changed/effected .

Any help will be really appreciated.
