Passing params to live_render/3 - ed component

When using live_render/3 to “render a LiveView inside a regular (non-live) controller/view”, is there a way to pass params to it? I mean other than storing them inside session? Even though mount/3 accepts params as its first argument I see no obvious way of getting them through when not “mounted at router”. Shovelling everything into session is an option but maybe I miss something here?
