While running a larp a number of years ago, my partner had a philosophy that took me some time to get - but now it's bread and butter at any ttrpg I run. I tell players that anything they know, their character also knows, regardless of the source. If players want an IG reason, I provide a plot line for that. But players don’t usually care after a discussion about it. If I can’t be creative enough to engage the minds of my players – allowing their knowledge to be true to what they actually know – then I need to spend more time creating. It does take more time and energy.
Metagaming could also mean that a player tries to ignore what they know, which is impossible, though that's what acting is all about. I've seen folks simulate such things with excellent quality, but I don’t hold players to the position of ‘your character only knows what they know’. They are free to play the game this way or not, but we shut down OOG debates about it right away. Those discussions are a waste of fun IMHO - whichever way you slice it.
