ᐅ Should the hydraulic balancing and individual room control be deactivated?

Hello everyone!
Since the heating season is slowly but surely starting again, I would like to begin adjusting our heating system (Viessmann Vitodens 200W 13 kW).
We built to KFW 55 standard with underfloor heating.
I keep reading about the hydraulic balancing. I would like to check and possibly readjust it!
Our heating technician was very committed… but not much more than that! That’s why I want to check everything myself.
How do I readjust the hydraulic balancing?
I set all room thermostats to full power (room temperature to 30°C (86°F) for example) and then check the “sight glasses” on the manifold to bring all flows to the same level, or am I misunderstanding something?
Since we have a weather-compensated system, does that affect anything?
If the balancing is correctly adjusted, what should I do next?
I would like to deactivate the ERR (electric radiator valves). How do I do that? Can I simply unplug the motors? Would they then be fully open?
If the ERR is deactivated (whatever the procedure), how do I then regulate the room temperature? Only by adjusting the flow or return water temperature of the heating system?
I would like to keep the weather-compensated control (is that possible?). Then I guess I would have to adjust the rest theoretically via the heating curve, right? How does that work?
It would be great if some experts here could offer me a bit of guidance.

Our whole house was sometimes too hot and sometimes too cold this spring (when we moved in)... That is normal during the initial period, especially since you haven't experienced a heating season yet. Construction moisture also plays a role. The response of underfloor heating, insulation, and so on...

Is the flow fully open on the side of the “actuators” then?Whether you remove them completely or leave them on with the visible red ring makes no difference. Open is open.The flow rate is limited by your circulation pump and the flow resistance of the underfloor heating pipes (caused by their length).
You only have a certain (finite) force F that can act on the system, and this force is distributed across all the heating circuits.
But yes, feel free to remove the motors completely.
