Show up for the people you love, even if this isn’t your thing. My sister in law had a gender reveal. I can’t stand those parties, but I still went. It’s for them, not for me. How I feel about the party doesn’t matter. What matters is making sure they feel loved and supported. The officiant at our son’s naming noted how strange it is that many show up for funerals, but pass on the opportunity to show up for joyful things. Show up for the joyful things, even if you don’t “understand” them.
To answer your other question, gifts aren’t usually expected at gender reveals here in the US. If you don’t want to go empty-handed you could always bring a plate of treats.
