I cannot, since that is totally "transparent" to the pilots in the FCOMs. No reference at all. However as it happens I researched a little about fbw control laws and I found that there is pitch factor blended at low speeds.
It is called a C* law. B777 has a C*U, the U being the trim speed thing. C* is a pitch rate and g load law, the proportion of both depending on speed.
Surf the internet, you will find plenty of stuff.
