I can’t even comment on generic “Agile” because it is so vague as to be meaningless.
Many teams I have worked with who have been successful work out their own process but slap “Kanban” on it as a label. It may or may not be Kanban, but by calling it Kanban, it is “acceptable” by TPTB as acceptably checking the agile box for management.
This is totally legit. Kanban is nothing more than tracking work by using tickets on a board organized by priority and status. It does not entail any Agile ceremony at all. I don't think it even requires that you track all the work on the board.
It's a very lightweight system that most can benefit from.
