Is there a way to remove content-security-policy: frame-ancestors 'none'; from server's header?

As a developer I was asked to create a demo App that shows our several Shopify pages via iframe.

I can see “content-security-policy: frame-ancestors ‘none’;” header added to Shopify server’s response.

That blocks pages to be embed via iframe.

So is there a way to disable this header through some settings?

Thanks

Not from the Admin settings, though if you contact Shopify support and ask them, they should be able to toggle a flag for you that will allow you to render the store in an iframe.
