There are a few ways of going about it. One is third parties. If you vote for the Green Party for example, you get voting reform, anti genocide policies and a much better enviromental policy. At the same time Biden is still much better then Trump and being realistic about what you can get should also be part of voting strategy. Also it is incredibly important to say, that citizenship does not end at the ballot box. You got to and can do more to influence politics. So I would probably vote Biden in a swing state and Green Party in an state, which is not a swing state. This matters in two ways. Firstly the more people vote third party, the more likely they can get into some actual power, but also the Democrats see that they can gain potential votes, by improving policies.
Also no lesser evil has to be distinguised from compromise and deals. If you get an actual improvement out of doing something, it can be worth doing even at a price. So if two countries face a powerfull invader, it can be worth making a deal that country A gets 40% of the invaders land and country B also 60%, if country B is already stronger for example. In that case both get something out of it. However without the alliance both would probably fail. In this case the question is, if Biden would actually net improve the US compared to today.
The point of the hypothetical is to demonstrate why the principle of lesser evilism is incorrect. Not every deal has to be exactly equal, the question is what to do when offered a terrible deal when the other party needs you just as much as you need them, and the answer is to bargain even if it means a risk of the deal falling through.
