GDO blaQ web UI doesn't support proxying through Authentik

I have a GDO blaQ on the latest firmware. I’m proxying it through Authentik so users on my network can access its web interface with authentication. When I do so, connections via Authentik to the GDO blaQ fail with HTTP 431 and the message:

Header fields are too long

Brief searching suggests this is a default ESP32 limitation and can be raised with the option CONFIG_HTTPD_MAX_REQ_HDR_LEN. Is there enough RAM to raise this value in future firmware builds?
