What would it take to keep the Nazis content with conquering Western Europe and never come up with an invasion plan of the UK in the first place? By this I mean that Operation Sealion is never put together and something makes Hitler decide that the invasion of Britain isn't worth it at all, as opposed to OTL where he obviously had to go through the Battle of Britain first before calling the invasion off.
Would there still be a Battle of Britain, albeit with different objectives? What would the consequences be for Eastern Europe, Barbarossa, and whenever *D-Day occurs?
