Any idea on how to re-render the scene using forward rendering after deferred?

I am using Unity 2021 with URP, and I am wondering if how would I go about rendering the scene using deferred rendering then re-render the scene using forward rendering? Mihoyo, the makers of Genshin Impact was able to do this so that the deferred rendering takes care of the lighting then re-render the scene using forward rendering for the unlit character models and for transparency materials to work. Also, would doing this affect performance?
