Not really.

If you’re not in a swing state then you could throw your support behind your preferred third-party candidate, or write in the name of literally any person you can think of who would cut off aid to Israel.

But not voting just says you’re OK with whomever the other voters pick for president. It says you don’t see a meaningful difference between Biden and Trump. And if you honestly don’t, OK, you’re allowed to think that. But in November, unless one of them dies, either Biden is going to win the election, or Trump is. The want to discourage people from voting against them. If you’re not voting you’re neutral so they don’t care as much.
