Unless you have very nice Sys Admin, and we are few and far between 😉, then I doubt it very much! You can only load (dl()) in either the default or set extension_dir.
There is the security issue which is why you probably wouldn't be able to presuade he/she to do this, unless I'm wrong and your the admin, then you can do what ya like 😃
You could always ask for the module to be compiled in/added on.
HTH,
