Are the Hall of Shame Episodes Canon?

[King of TV]

I've been binging shameless on Netlfix, and I'm almost done the show, I just started wrapping up the ninth season. As for the Hall of Shame, do I need to watch those, or are those just extras and bloopers. I avoided looking deeply into it because I don't want spoilers.

Canon is a strong word to use with Shameless, but I don’t they rewrite any history.
