Yes, but it's no mode, it's a simple variable you can set.

,----[ C-h v header-line-format RET ]
| header-line-format is a variable defined in `C source code'.
| Its value is nil
| 
|   Automatically becomes buffer-local when set in any fashion.
|   This variable is potentially risky when used as a file local variable.

| Documentation:
| Analogous to `mode-line-format', but controls the header line.
| The header line appears, optionally, at the top of a window;
| the mode line appears at the bottom.

I guess you could redefine the function `eldoc-message' and set
`header-line-format' there.
