A10M Prime Tower always two colors

[PrebenGH]

I am using Cura 4.1 to generate my files for two color printing with A10M.
When printing a part that is one color for the first many layers, I still get a prime tower with both colors.
I am using a 20 mm square prime tower with 40 mm3 volume for each extruder to get a solid tower.
The result is that I get a prime tower with color 1 for the outer rings, then color 2 for middle rings and finally color 1 again for the center. For the first many layers color 2 is not required.
Is there a setting in Cura 4.1 to only use one color in the prime tower when the other color is not used for the particular layer?

I was not able to make the scripts working tough. Gcode M211 does not seem to work with my A10M, I don't know yet why (Marlin 1.8 ?).
