As hard as it is, leaving in the mid-term may be the best option. i can only talk for myself, but when my supperior doesn't think I'm on board I can't go "on board" or fake it realistacally. Well, I can long enough to find something better.
For the meeting itself, not so easy.
Part one: Come up with a plan for the meeting. Best if you know what "on board" means and come up with some believable actions or things you can do in the future showing you ARE. Find some explanations why you were not in the past, even if it means to only find expalnations why your boss thinks you're not "on board".
Maybe you even know what kind of agenda your boss has for himself, this adds a lot of usefull context to the points mentioned above.
Part two: Use the time you bought yourself to find something better elsewhere. There are people that can addopt enough and get "on board" (whatever that really means), but I'm none of those.
In cases like this, it's all about how a situation is percieved and not how it really is.
Hope it helped a little bit. And even if it's not easy, don't worry or even panic, stay calm and polite. Be prepared, but don't argue any points before they are brought up by someone else.
Disclaimer: Had one meeting like that myself, came up with a defense a couple of weeks later, left 4 months later. Teached me to be prepared for meetings like this.
