Permit modification of request headers during WebDAV protocol access

I possess a WebDAV server; however, for security reasons, the administrator has mandated the utilisation of specific request headers to facilitate the transmission of files exceeding 5MB in size. Currently, I am only able to execute such downloads via the terminal. Could you please advise whether your system supports the functionality of modifying request headers?

No, there's no such option. Can you share details about the header and the WebDAV server?
