VueScan doesn't allow you to pick a focus point either.

The SS120 seems to use a fairly sophisticated focus algorithm
that first does a rough sampling of the whole image, and then
a fine focus at some position that it chooses.

VueScan (and Insight and SilverFast) just set a single
bit at the start of the scan to tell the scanner to auto focus
before scanning.
