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.
