Enabling Level 2 WebDAV on nginx

Question

When I mount my nginx WebDAV server as a macOS volume, it is mounted as read-only.

I've read the suggestions on this page but they use the more_set_input_headers which is not available on my nginx-full Debian package.

I've tried adding the nginx repository and adding the module manually with:

curl -fsSL https://nginx.org/keys/nginx_signing.key | gpg --dearmor -o /usr/share/keyrings/nginx-archive-keyring.gpg
ano /etc/apt/sources.list.d/nginx.list

# added
deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] https://nginx.org/packages/debian/ bookworm nginx

apt-get update
apt-get install nginx-plus-module-headers-more # not found

Apparently this module is only available with the commercial nginx Plus package.

The WebDAV server works as expected if I use Cadaver but I'd like to mount it as a Finder volume (as well as a Windows network drive).

1. Is there any way I can accomplish this behavior with the regular nginx distribution?
2. Will I have the same problem if I switch to Apache?

Thanks.
