El Camino before or after Better Call Saul S6?

[BEFOREHAND PRECAUTION: PLEASE DON'T GO TOO INTO DETAIL] So I'm nearing the end of the Breaking Bad series and am going to watch the first 5 seasons of Better Call Saul right after. My initial plan was to watch El Camino after both TV Shows but I learned that Season 6 holds spoilers for El Camino. What I want to know is: does Season 6 by any chance casually drop a major plot point in El Camino like it's nothing? Or is it the most minor things like something about potatoes? Also to reiterate please don't say what happens ToT just tell me whether or not something is referenced from El Camino in Season 6 and whether or not it's a big deal
