I'm not sure how much is by law and how much is by executive order, but I believe that when Biden gets in, he could make some changes unilaterally.

So, essentially this would be about advocating for change by the Biden administration. It wouldn't be by voting (since the election is already done), but writing to your representative could help. Maybe there are advocacy groups that could use support?

Advocating for changes is more likely to be effective with an administration that isn't fundamentally opposed to them.
