Possibly, but it would not be easy. You would have to use struct() on the heatmap object in order to get at internal parts of it, and you would have to figure out exactly which internal part to change.
For example it turns out you can change some of the text by recording the heatmap handle (call it HH) and altering
HS = struct(HH);
HS.Axes.Box = 'off'
has no effect.
and digging in to
HS = struct(HH);
Hg = struct(HS.Heatmap.Grid);
and trying to set the grid properties has no visible effect.
heatmap objects are unfortunately barely customizable through supported interfaces.
