FWIW, passing environment variables from Apache httpd to PHP-FPM via a
Unix socket works just fine, e.g.:

  SetHandler "proxy:unix:/run/php/php7.3-fpm.sock|fcgi://localhost"

or similarly using another method and another server process (uWSGI)
and protocol (httpd also loading mod_uwsgi):

  ProxyPass / unix:/run/uwsgi/some_app.socket|uwsgi://localhost/

The only thing I could easily find for ASGI (which I haven't used
myself so far) with the uWSGI server seems to be stale/abandoned,
