Yeah of course that is possible. With the US system though it seems like there is literally no point. If you don't want trump you should vote for Biden, that is the only choice.

But the fact that this is brought up every time Biden does something shit or supports a genocide or whatever is what I take issue with. The election has made people too wary to criticise him and they are apparently blind to how stupid this looks. Like they learned nothing whatsoever from 2016.

Anyway I'm not American anyway so don't worry about it. The situation is the same in the UK except Labour is comfortably going to win anyway despite having a dog shit candidate. Biden I'm not so sure, and that worries me.

The third (minor) parties are just spoiler candidates put in place or at least supported by the two major parties.
