Answer 1

If you want to completely bypass flask and use purely Jinja for rendering your template, you can do as such

import jinja2

def render_jinja_html(template_loc,file_name,**context):

    return jinja2.Environment(
        loader=jinja2.FileSystemLoader(template_loc+'/')
    ).get_template(file_name).render(context)

And then you can call this function to render your html
