It's very much possible. Look up Noah Hannibal, Nimai Delgado, John Thomas, Brian Turner, Lifting Vegan Logic, Lakshay Naidu, Patrik Baboumian.

They all eat Tofu and other soy products like edamame regularily, often for decades and can't exactly be called feminized.

So tofu is really your friend. Many benifits like high calcium content, isoflavones preventing specific cancers and the most complete protein in the plant world, IIRC. Quinoa and hempseeds have a pretty good amino acid profile too but are more cumbersome to consume than tofu. It tastes bland on itself but it can transform into many delicious dishes if prepared right.

If you want to learn more about the body building aspects you find a ton of information on the respectice YT channels of above mentioned body builders.

I'd refer to these channels if you want to learn how to cook good whole food plant based dishes:

I mean, I think it's fine to make sure your diet contains all these things. If you're eating vegan (even if you're not) yeah, do eat beans/lentils/soy etc., for sure. But I think stressing is overkill. If you just eat a good variety of foods you're likely to get what you need.
