You can use an overlay
Or you can use bwboundaries() to get the outline of the region and then use plot() to put up a colored outline.

Starting in R2024a, xline, yline, xregion, and yregion all support the ability to appear both behind and in front of objects in an axes using the Layer property:
plot(1:10, LineWidth=4);
x1 = xline(2,LineWidth=4,Alpha=1);
x2 = xline(3,LineWidth=4,Alpha=1,Layer='bottom');
x3 = xregion(4,5,FaceAlpha=1);
x4 = xregion(6,7,FaceALpha=1,Layer='top');
The default for ConstantRegion (the underlying object for xregion and yregion) is to appear in the 'bottom' layer and the default for ConstantLine (the underlying object for xline and yline) is to appear in the 'top' layer.
