Do you use the default temperatures for the 0.4mm and 0.6mm nozzle or did you change those values in the firmware?

Have you tried calibrating the extruder to see how much your outing out

I've changed, I've tried different temperatures from 206 to 210 degrees Celsius.

No, I did not even try because I did not know how to do it.
How do I do this calibration?

That's not too much. You may vary temperature a bit more, but don't go over 230°C for PLA.
I don't say this is your problem but it would not hurt to check what your system is doing, personally I would check.
Hi to all !
Hi paul9 !

I think bob-hepple is right,
Independently of the material diameter use,
The extruder Estep calibration was the first thing to do, it's easy to do if you use the Tinkergnome firmware. ( hightly recommanded)
If use the UM2+ Extruder , here the process
With the rotary button, clic on Tinker control board
Advanced
Preference
Motion settings
Axis steps mm
clic on E "nnn.nn" the value indicated (note this)
clic on it to change it by this new value : 341.62
do not forget to clic on "Store" before go back
Done !
This will be a good average base, (may be it will need to adjust a bit if use the Tom's guide process for sample)
Here the math formula
Esteps/mm = (Nr.motor steps rev * Nr.driver micro steps) * (Nr.big gear teeth / Nr.small gear teeth) / (effective grooved gear diameter * PI)
Extruder UM2+ - Nema 17-200-16 and 36T/11T reduction gears
Deep groove gear diameter 9.75mm
(200*16) * (36/11) / (9.75*3.1416) = 341.62
I don't say this is your problem but it would not hurt to check what your system is doing, personally I would check.
Thank you Bob!

Thank you Gudo,
But I understand after some considerations that actually the problem is not overextrusion but cooling. I can not immediately cool the material while printing and create an effect that seems to be over extrusion.

In some cases, without changing the flow, I have the acceptable vertical print portion even though it always has a bit of over-extrusion and then the horizontal parts in under-extrusion.
