I would not try to make goals less exciting. I would just make the rest of the game more visible.
After matches, ask different questions: “What did you enjoy?”, “What did you do that helped a teammate?”, “Was there a moment you defended really well?” That widens the conversation without pretending scoring is not special.
Adults can also change the compliments they give. Instead of always asking “did you score?”, say “tell me about the game.”
If she scores, celebrate it. If she does not, there should still be plenty from the match that feels worth talking about.
Children notice what adults repeatedly value.
If every car journey, grandparent conversation and sideline reaction points back to goals, it is understandable that she starts using goals as her own scorecard too.
