Kind of, yeah. Supreme court justices aren't elected, are appointed for life, and collectively have veto power over basically any law, should they choose to break (or gradually discard) historical norms.
I think it's telling that neither Biden nor Harris was willing to rule out court-packing at the presidential debates, and at this point I think they're right to leave it on the table! But, it really would mark the beginning of the end of the Supreme Court. It's easy to predict what would probably happen the next time power changed...
