Does anyone know how to Disable/remove Do you want to view _ in full screen? Notification bar when viewing video in full screen in IE 11 for all websites?

Internet Explorer 11 notification bar

Stupid, annoying bar always asks me "Do you want to view
www.youtube.com in full screen? (Press Esc to exit.)" Is there anyway to disable it?

 

How do I disable "do you want to open game bar"?

As annoying as it is, you can't in Internet Explorer.

All you can do is select 'Always Allow' full screen for individual websites, however when you clear your browsing history it will reset that setting because the settings for it are stored under the 'History' (list of websites you have visited) section.

Microsoft Edge can remember this setting separately so that when you delete your browsing history your full screen permissions aren't also reset, but obviously that's of little help for those who prefer using Internet Explorer to Edge at the moment. And it's still not an 'all websites' setting, you still get a dialogue box for individual websites, it's just possible to remember your setting now.
