Can't you simply spin the fly by wire focusing ring to the "infinity"
end of its travel? I just tried that with my A1 and it works fine. The
ring keeps turning but the distance reading on the screen stays at
ininity. Perhaps you don't have a focus distance readout anywhere but
you can probably experiment and discover that, for example, if you turn
the ring at least one full turn you're at infinity.
I went to try the same thing with the 5D and Tokina 28-80 forgetting
that the Tokina has a distance scale and an infinity mark and a hard,
mechanical stop when in manual focus mode.
