Yes; in fact the default is for zsh/main to be static-linked and all the
other modules to be dynamic.

That's the way you're supposed to do it.  However, I think you may be a
little confused about the procedure:

That's the first mistake.  You want one of

	configure --enable-dynamic			(the default)
or
	configure --disable-dynamic

Do not specify the -static or -shared ldflags yourself directly; they are
independent of whether individual modules are static-linked.

For a mix of static and dynamic modules, you must start by configuring a
dynamic shell, then edit config.modules to select the modules that you
want linked static.

Did you ever actually edit config.modules to set "link=static" for zftp?
If so, did you also set "auto=no" so that re-running configure would not
clobber your changes?

The INSTALL file should tell you just about everything you need to know.
